Connext (Everclear) (connext)

Cross-chain liquidity protocol rebranded as Everclear. Uses intents and a clearing layer for capital-efficient cross-chain transfers.

Fact	Value
Category	Bridges
Family	none
Namespace	`Connext` on ethereum, optimism, base, arbitrum
Chains	ethereum, optimism, base, arbitrum

Notes

Intent-based architecture: users express desired outcome, solvers compete to fill
Rebranded from Connext to Everclear — same contracts
Same EverclearSpoke address deployed across all chains
Uses domain IDs (uint32) for destination chains, NOT EVM chain IDs
Supports cross-chain swaps (inputAsset != outputAsset)
ttl determines how long the intent is valid — unfilled intents can be cancelled after expiry
Finality: typically 2-15 minutes depending on solver activity
Requires ERC-20 approval to the EverclearSpoke

On Ethereum, Connext is a namespace: its contracts need no import.

function main() {
  // Ethereum's everclearSpoke, `0xa05A3380889115bf313f1Db9d5f335157Be4D816`.
  require(Connext.EverclearSpoke != 0);
