Stage 1 of the two-stage withdrawal flow. Validates the request, checks live onchain balances, and returns an EIP-712-typed authorization message the end-user signs with their portfolio owner wallet. Stage 2 (POST /v2/portfolios/{portfolioId}/withdraw) accepts the signed envelope and dispatches the onchain transfer. Wallet addresses are exchanged as CAIP-10 account identifiers. recipientAccountId uses the chain-bound EVM form eip155:<chainId>:<address> — a withdrawal always goes to one address on one specific chain. Only EVM recipients are supported today.
  • Auth: x-api-key header (required)
  • Scope: portfolios:withdraw
The returned authorizationId (= the signed message.nonce) is the idempotency anchor for the matching POST .../withdraw call. Stage 1 returns the full EIP-712 typed-data object at data.typedData — pass it directly to signTypedData(data.typedData) in the user’s wallet. On stage 2 the integrator echoes back typedData.message as body.message alongside the signature. The authorization is valid for 10 minutes. If the user takes longer to sign — or a balance check fails at stage 2 — restart the flow by calling this endpoint again.

​
Chain-equivalence rule

Every asset’s assetId must be on the same chain as recipientAccountId. A single authorization withdraws a set of assets from one chain to one recipient on that chain. Multi-chain withdrawals require separate authorizations per chain.

​
Signed EIP-712 domain

The returned domain binds the signature to two things:
  • chainId — the EVM chain the assets and recipient live on. Required for ERC-1271 smart-wallet verification, which re-hashes the typed-data using the wallet’s own chainId.
  • verifyingContract — the smart account being debited on that chain. Scopes the signature to a specific smart account deployment.
Integrators should pass domain, types, primaryType, and message verbatim to signTypedData in the user’s wallet.

​
What the user sees in their wallet

When rendering the signature prompt, the wallet displays each field of the signed struct. Users see recipientAccountId as a CAIP-10 string like eip155:1:0x4444… — chain and address are visible together. They also see portfolioId, assets (CAIP-19 asset ids + raw atomic amounts), nonce, and expiresAt. Integrators SHOULD surface a decoded summary in their own UI (asset symbols, human-readable amounts) so users can verify the recipient and amounts before approving. Common error responses:
  • 400 API_210 INSUFFICIENT_BALANCE — live balance below amountRaw for at least one asset.
  • 400 API_211 INVALID_RECIPIENT — zero address, smart account self-transfer, or non-EVM namespace.
  • 400 API_212 DUPLICATE_WITHDRAW_ASSET — two or more assets in assets share the same assetId.
  • 400 API_213 WITHDRAWAL_CHAIN_MISMATCH — at least one asset is on a different chain than recipientAccountId.
  • 400 API_215 PORTFOLIO_HAS_NO_VAULT_ON_CHAIN — portfolio has no smart account deployed on the recipient’s chain.
  • 400 when the request body is otherwise invalid (schema errors).
  • 401 when x-api-key header is missing or the key is invalid.
  • 403 when the API key lacks the portfolios:withdraw scope.
  • 404 API_200 PORTFOLIO_NOT_FOUND — portfolioId doesn’t exist or belongs to a different tenant.
  • 500 on unexpected server errors.
