Intents Connect is Aurora's cross-chain execution layer. A user with a wallet on one chain performs an action on another: no manual bridge, no dest-chain wallet switch, no dest gas hunt. The docs example is a Solana wallet depositing USDC into Aave on Ethereum. The user signs one intent. Everything else is handled.

It is powered by NEAR Intents. The 1-click swap surface stays on NEAR Intents 1-click. Connect is the execution API and widget for protocol actions, not just a swap.

How it runs

The backend builds a typed message: source chain, dest chain, asset, amount, target protocol, fees, expiry, nonce. The user signs that message and deposits the source asset to a designated address. Near Intents converts the asset and funds an intermediary account on the dest chain. That account, owned by the origin wallet and controlled via Chain Signatures (MPC on NEAR), runs the dest transaction.

Lifecycle: CREATED → DEPOSIT_PENDING → DEPOSIT_PROCESSING → OPERATION_PENDING → OPERATION_PROCESSING → SUCCESS. One intent authorises one bounded outcome. Nonce plus expiry block replay. Failure surfaces to the UI; recovery needs another user signature because Intents Connect does not control the intermediary account.

Solana

On the live supported-chains table, Solana is a source and a destination. Dest type is evm or solana (default evm). Solana steps are ExecutionStepSolana under the same steps key. Cap: 50 Solana steps, 30 EVM steps. Solana supports bridge-in and out-operation, plus a gasless SPL model where a relayer pays the network fee in the dest token. Address lookup tables compress v0 transactions. 503 if no durable nonce account is free. Origin wallet path params accept Solana base58 keys.

API

Host: https://intents-connect-api.aurora.dev. Header x-api-key from studio.aurora.dev. Keys are not confidential. Fees split 60% integrator / 40% Aurora, Aurora floor 2 bps, max 100 bps.

text
POST /api/v1/executions/{wallet}
Header: x-api-key
type: evm | solana

Also: list tokens, fetch executions, request steps execution, fetch intermediary accounts, delete an execution, submit digest, submit deposit hash. Widget path if you want UI instead of the API.
