Kaspa to Solana Bridge
A Kaspa to Solana bridge exists, but it is new. Since February 2026 Dymension lets you send KAS to Solana and get a KAS token there, routed through its own network. It is labeled experimental and the token barely trades yet. For most people, swapping KAS to SOL on an exchange or swap service is still the easier path.

Short answer
Short answer: yes, there is now a Kaspa to Solana bridge, but it is early. Dymension announced it on February 18, 2026. You lock KAS on Kaspa, a group of Dymension validators confirms the deposit, and a KAS token is created on Solana. If you only want SOL or USDC, skip the bridge and swap KAS to SOL on an exchange or an instant swap service. That takes 10 to 60 minutes and has far more buyers and sellers.
The bridge is for people who want to keep holding KAS but use it inside Solana apps. The catch is that KAS on Solana is new. When it launched, there was hardly any place to trade it, and the Dymension developer tools still call the Solana route experimental. Your KAS is backed by an escrow wallet on Kaspa that needs signatures from several validators to release coins, so you trust that group not to collude or get hacked.
Kaspa itself is changing fast. Smart contract layers such as Kasplex and Igra Network now run on top of Kaspa, and the Toccata upgrade in June 2026 added tools that could make safer bridges possible later. None of that gives you a bridge to Solana with no trusted signers yet. Below we compare the options, show the simplest way to swap KAS to SOL, and list what to watch.
| Direct bridge | Yes, early (via Dymension) |
|---|---|
| Bridge type | Validator multisig, routed via Dymension |
| Usual way | Swap KAS for SOL or USDC |
| Usual swap time | 10-60 min |
| KAS on Solana liquidity | Very thin |
| Kaspa address | Starts with "kaspa:" |
| Solana address | Base58, 32-44 characters |
Why this route is difficult
Kaspa and Solana are built very differently. Kaspa is a proof-of-work blockDAG that makes 10 blocks per second and keeps coins in UTXOs, like Bitcoin. Until recently its main layer had no smart contracts at all. Solana is a fast proof-of-stake network with accounts and programs. Neither one can easily check the other's blocks.
Without that, a bridge needs someone to hold the real KAS. In the Dymension bridge, KAS sits in an escrow address on Kaspa that needs signatures from a set of Dymension validators. They confirm deposits and sign withdrawals, and the token then travels from Dymension to Solana over Hyperlane-style messaging. It works, but you trust that group and two hops of software.
There is also an economic problem. A bridged token is only useful if people trade it. KAS mostly trades on centralized exchanges, and Solana DeFi has little demand for KAS so far. Thin pools mean bad prices, which keeps users away, which keeps pools thin.
Kaspa's Toccata upgrade in June 2026 added covenant-style scripts and zero-knowledge proof checks. In theory these could let Kaspa itself enforce bridge rules instead of relying only on signers. That work is new, and no Solana bridge uses it yet.
Past attempts
| Project | When | What happened |
|---|---|---|
| wKAS by Chainge | 2023-present | Custodial wrapped KAS on Ethereum and BNB Chain. It still exists, but trading is tiny and the price has drifted far from KAS. It never reached Solana. |
| KRC-20 tokens (Kasplex protocol) | 2024-present | Brought tokens to Kaspa itself, not bridges. Useful for Kaspa projects, but it did nothing to move KAS to other networks. |
What is being built
Dymension Kaspa bridge
Mainnet betaValidator multisig bridge from Kaspa to Dymension, with onward routes to Ethereum, Base, BNB Chain and Solana. The Solana route went live in February 2026 and is still called experimental.
Igra Network (Igra Labs)
MainnetAn EVM layer that uses Kaspa to order its transactions. It brings smart contracts to Kaspa and could host bridge contracts, but it has no Solana bridge of its own.
Kasplex L2
MainnetAn Ethereum-style layer on Kaspa that uses KAS for fees. It gives Kaspa apps and wallets like MetaMask, but not a link to Solana.
Toccata upgrade
ResearchActivated on Kaspa in June 2026 with covenant-style scripts and zero-knowledge proof checks. Bridges that rely on proofs instead of signers are now being explored, not built.
What still stands in the way
- Kaspa and Solana cannot check each other's blocks cheaply, so bridges still depend on trusted signers.
- KAS on Solana has very little liquidity, so bridged tokens are hard to sell at a fair price.
- The Dymension route has two hops (Kaspa to Dymension, then Dymension to Solana), and each adds risk.
- Most KAS trading happens on centralized exchanges, which gives DeFi users little reason to bridge.
- Proof-based bridge tools on Kaspa are brand new after Toccata and not yet tested in real use.
Signs the bridge is close
- A KAS on Solana pool with real depth on Raydium, Orca or Meteora, and Jupiter quoting it.
- Dymension dropping the experimental label on its Solana route, or publishing an audit of the Kaspa bridge.
- A bridge using Toccata covenants or ZK proofs announced with a public testnet.
- NEAR Intents, THORChain or Chainflip adding native KAS, which would let you swap straight to SOL.
- Phantom or another big Solana wallet listing KAS on Solana by default.
Possible approaches
1Swap to SOL
Sell KAS on an exchange or instant swap service and receive SOL or a stablecoin on Solana.
Trade-offEasy and liquid. You give up KAS, and the service holds your coins for a short time.
2Validator multisig bridge
Lock KAS in an escrow controlled by a group of validators and receive a KAS token on Solana. This is how Dymension works.
Trade-offYou keep KAS exposure, but you trust the validators, and the token is hard to trade for now.
3Via a stablecoin
Sell KAS for USDT on an exchange, then withdraw USDT or buy SOL and withdraw on Solana.
Trade-offWorks on almost any exchange that lists KAS. Two trades, two sets of fees.
Options compared
| Option | You get | Typical time | Cost | Best for |
|---|---|---|---|---|
| Centralized exchange | SOL, USDC or USDT on Solana | 10-60 min | Trading + small SOL withdrawal fee | Most people, larger amounts |
| Instant swap service | SOL or a stablecoin | 10-40 min | Markup in the rate | One-off swaps, no exchange account |
| Dymension bridge | KAS token on Solana | Minutes to an hour | Bridge and network fees | Keeping KAS exposure inside Solana apps |
| KAS to USDT, then to Solana | USDT or USDC on Solana | 20-60 min | Trading fee + withdrawal fee | Exchanges with no KAS/SOL pair |
Working solutions
| Solution | You receive | Custody / verification | Notes |
|---|---|---|---|
| Centralized exchanges | SOL, USDC or USDT | Exchange holds funds | Most liquidity. Deposit on plain Kaspa, withdraw on Solana. |
| Instant swap services | SOL or stablecoins | Service holds funds briefly | Several list KAS to SOL. Rates include a markup and terms differ. |
| Dymension bridge | KAS token on Solana | Validator multisig on Kaspa | Live since February 2026, still marked experimental. Very little trading on Solana. |
How to move Kaspa to Solana
These steps show how to swap KAS for SOL on a centralized exchange. It is the path with the most liquidity today, and many large exchanges list both coins.
- 1
Get your Solana address
Open Phantom, Solflare or Backpack and copy your Solana address. It is a mix of letters and numbers, usually 32 to 44 characters, with no 0x at the start. If you plan to receive USDC or USDT, keep a little SOL in the wallet too, so you can pay fees later.
- 2
Get the KAS deposit address
On the exchange, open the KAS deposit page and pick the main Kaspa network. The address should start with "kaspa:". Some exchanges also list KAS on other networks. If you send from a normal Kaspa wallet, choose plain Kaspa.
- 3
Send KAS from your wallet
Send from Kasware, Kaspium or Kaspa NG. The Kaspa fee is tiny. Send a small test first if the exchange is new to you, and check the minimum deposit so your coins are not stuck below it.
- 4
Wait for the deposit
Kaspa confirms in seconds, and you can follow it on explorer.kaspa.org. The exchange still waits for its own number of confirmations, which usually takes a few minutes.
- 5
Sell KAS for SOL or a stablecoin
Many exchanges have no direct KAS/SOL pair. If so, sell KAS for USDT first, then buy SOL with it, or keep the USDT. Use a limit order for larger amounts so you do not move the price against yourself.
- 6
Withdraw on the Solana network
Choose Solana (sometimes shown as SOL or SPL) as the network. Paste your address and check it. Solana withdrawals usually arrive in under a minute once the exchange sends them. Look up your address on Solscan to confirm.
Fees and timing
The Kaspa side costs almost nothing, usually a fraction of a cent. On an exchange you pay a trading fee, twice if you go KAS to USDT to SOL. Solana withdrawal fees are small compared with Ethereum. With an instant swap service there is no separate fee, but the markup is built into the rate, so compare a few quotes.
On the Dymension bridge you pay network fees on Kaspa and Solana and a bridge fee shown in the portal. The bigger hidden cost is selling KAS on Solana later. With so little trading, the price you get can be far below the KAS market price. Check a pool before you count on it.
Time depends mostly on the service in the middle. Kaspa makes 10 blocks per second and Solana is just as quick, so the networks are not the slow part. Exchange confirmation rules, manual checks and bridge relayers are.
Common mistakes
- Bridging KAS to Solana when you only wanted SOL. A plain swap is simpler and avoids holding a token that is hard to sell.
- Buying a "KAS" token on a Solana DEX without checking the mint address. Fake tokens with the same name are common. Use only the address shown in the Dymension portal.
- Picking the wrong withdrawal network on the exchange, such as BNB Chain or Ethereum, instead of Solana.
- Receiving USDC or USDT on Solana with no SOL in the wallet. You need a little SOL to move tokens.
- Sending less KAS than the exchange minimum deposit. It may not be credited without a support ticket.
- Treating wKAS from Chainge as KAS on Solana. wKAS lives on Ethereum and BNB Chain, not Solana.
Before you transfer
- Decide first whether you need KAS on Solana or just value on Solana. For value, a swap is simpler.
- If you bridge, start small and test the way back to Kaspa before moving a larger amount.
- Check how much KAS on Solana actually trades before you bridge. A token you cannot sell is not much use.
- Use only the token address shown in the official Dymension portal.
- On exchanges, check both the deposit network (plain Kaspa) and the withdrawal network (Solana).
- Keep a little SOL in your Solana wallet for fees.
Frequently asked questions
Yes, an early one. Dymension launched a Kaspa to Solana route in February 2026. It locks KAS on Kaspa with a group of validators and gives you a KAS token on Solana. It is still marked experimental and the token has very little trading.
The simplest way is an exchange or instant swap service. Send KAS on the Kaspa network, swap it for SOL (or for USDT first if there is no KAS/SOL pair), and withdraw on the Solana network to your Phantom or Solflare address.
It is not trustless. Your KAS is held in an escrow address that a set of Dymension validators controls together. If enough of them misbehave or the code has a bug, funds could be lost. Treat it as early software and use small amounts.
Nobody has announced a date. Kaspa's Toccata upgrade added features that could help, and teams like Igra Labs are building on Kaspa, but no project has announced a trust-minimized bridge to Solana with a launch date.
No. wKAS from Chainge lives on Ethereum and BNB Chain. KAS on Solana comes from the Dymension bridge and is a different token.
Usually 10 to 60 minutes. Kaspa and Solana are both fast. Most of the wait is the exchange or swap service checking the deposit and sending the payout.
Not plain KAS. Plain KAS needs a Kaspa wallet such as Kasware or Kaspium. Phantom can hold the bridged KAS token on Solana once it is in your Solana address.
