}
Notes
  • The token field can accept either a token symbol (e.g. “USDC” or “USDT”) or a contract address (for EIP-155 tokens) or a mint address (for Solana tokens).
  • The amount should be provided in the token’s primary denomination (e.g. whole USDC, not micro-USDC).
  • This endpoint creates an unsigned transaction. The client is responsible for signing the transaction before broadcasting it to the network.
  • The response structure differs between Solana and EIP-155 chains. Make sure to handle both response types in your implementation.

​
Simulate + validate a transaction

POST https://api.portalhq.io/api/v3/clients/me/evaluate-transaction This endpoint evaluates a transaction by either simulating its execution or validating its authenticity (or both). The evaluation provides detailed insights into the transaction, including potential changes in asset balances, exposures, and a classification of the transaction’s risk.
