How moving coins between blockchains works
Blockchains cannot see each other, so coins never really travel. Here are the three basic ways value gets from one chain to another.

With intent bridges you state what you want, a solver pays you on the other chain from their own funds, and gets repaid later.

Every bridge relies on someone: a custodian, a signer group, a validator network or code. Here is how to tell who, and how to judge the risk.

A cross-chain transfer can include network fees on both chains, a protocol fee, a spread and price impact. Here is how to see the real total.

Chains without smart contracts, or with built-in privacy, cannot run a normal bridge. Here is why, and what your real options are.

57 terms, each explained in a sentence or two, with more detail if you want it.
- Canonical bridgeThe official bridge built by a network's own team, such as the Arbitrum or Base bridge to Ethereum.
- Liquidity bridgeA bridge that keeps pools of the same coin on several chains and pays you from the pool on the other side.
- IntentA request that says what you want ("100 USDC on Base") and lets a professional payer figure out how to deliver it.
- SolverA professional trader who pays you on the destination chain from their own funds, then gets repaid from your deposit.
- RelayerA service that carries messages or payments from one chain to another. In some bridges, relayers also front the money.
- Messaging protocolA system that lets programs on different blockchains send verified messages to each other. Bridges are built on top of it.
- Cross-chain swapTrading a coin on one blockchain for a different coin on another, for example BTC on Bitcoin for SOL on Solana, in one step.
- Atomic swapA direct trade between two people on two chains where either both sides complete or both get their coins back.
- AggregatorA tool that compares many bridges and swaps at once and shows you the best route for your transfer.
- LiquidityHow much money is available to trade a coin. More liquidity means you can buy or sell more without moving the price.
- Liquidity poolA pot of two or more tokens held by a smart contract that people can trade against. The price comes from the balance between them.
- SlippageThe difference between the price you were quoted and the price you actually get, because the market moved before your trade went through.
