Starknet Bridge: how to bridge to and from Starknet
Starknet is a zero-knowledge rollup on Ethereum. Its official bridge relies on validity proofs, so withdrawals finish once a proof is accepted on Ethereum, usually within hours rather than a week. Fast bridges still deliver sooner.
Quick answer
Services supporting Starknet: 2. Most used in our guides: StarkGate, Rubic. Direct transfers possible to: Ethereum, Bitcoin, Solana, BNB Chain, Arbitrum, Base, TRON.
Popular services
StarkGateCanonical bridge
Official Starknet bridge: the network's own route to and from Ethereum. Slower to withdraw, but no extra parties to trust.
Rubic
Rubic is a cross-chain swap aggregator running since 2020. According to its documentation, it compares more than 340 DEXs, bridges and intent protocols across 70+ networks and shows the best quote in one interface.

Only 2 of the projects we track support Starknet, so many pairs have no direct route and prices vary more.
Alternative ways to move funds
The official rollup bridge
The bridge run by Starknet itself relies only on Ethereum and the rollup. It is the safest option, but withdrawals to Ethereum are slower than with third-party bridges.
Move stablecoins instead
Converting to USDC or USDT and moving it through the issuer’s own transfer protocol often has the widest coverage and the least slippage. Swap back on the destination if you need another asset.
Through a centralised exchange
Deposit on Starknet, trade if needed, and withdraw on the destination network. Simple and often cheap, but the exchange holds your funds in between and needs identity verification.
Two steps through a well-connected chain
If no single route exists, first move to a chain with many connections (Ethereum, Solana or a major rollup), then on to the destination. It costs two fees, but each step uses a well-tested route.
How transfers work on Starknet
- The official bridge is the most trust-minimised route to and from Ethereum.
- Liquidity bridges and intent networks cover most rollup-to-rollup routes in minutes.
- Stablecoins can move through issuer transfer protocols where Starknet is supported.
What to watch out for
- Proof and finalisation times vary between rollups and can grow during busy periods.
- Smaller rollups are supported by fewer bridges, so compare quotes before you send.
