EvmWallet, and the SDK drives it. Do that once and every on-chain flow works: Ondo buys and sells, Superstate swaps, token-sale approvals, and wallet ownership proofs.
The pages in this section cover providers whose customers can plug Passage in, including what their wallets are, how keys are held, and what the integration takes on each side.

What a wallet partner has to satisfy
One interface, five members.EvmSigner covers address and signMessage, which is enough to prove wallet ownership. EvmWallet adds writeContract, broadcastRawTx, and awaitTx, which covers everything on-chain: approvals, swaps, and allowlist transactions.
The SDK ships viem types, so a provider that already exposes a viem account or wallet client is most of the way there. See Wallets for the full interface, the adapter pattern, and how wallet errors are classified.
Users keep custody throughout. Passage has no ability to access, recover, freeze, or otherwise control assets in a user’s wallet, whoever provides it. See Wallets and chains.
