How this service works
Interpreted wallet data for more than 40 chains and Solana: portfolios, DeFi positions, PnL, transactions and NFTs. REST for apps, x402 pay-per-call for agents.
Output
A JSON object containing a data field with the resource id, type, and attributes for the simulation signature result, plus a links.self URL pointing back to the Zerion API resource. Confirms whether the EIP-712 signature is valid and returns relevant simulation metadata.
Example use cases
Pre-simulation signature check
“Before I simulate this DeFi swap transaction, verify the EIP-712 signature for wallet 0x1234abcd... using this domain and message object to make sure it's valid on Zerion.”
Agent wallet authentication flow
“I need to authenticate my agent's wallet action by verifying the EIP-712 typed data signature — wallet is 0xDEAD...BEEF, here's the domain and message structure that needs validation.”
Smart contract interaction verification
“Can you validate this EIP-712 structured data signature from wallet 0xABC...789 against the provided domain and message before I proceed with the on-chain simulation on Zerion?”
Technical details
Endpoint
POSThttps://api.zerion.io/v1/wallets/simulation/signature?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate EIP-712 typed data signatures specifically in the context of Zerion's wallet simulation feature, especially for agents using x402 pay-per-call access. Prefer this over generic signature validation tools when working within the Zerion DeFi ecosystem across 40+ chains including Solana, where you need structured simulation verification as part of a broader portfolio or transaction workflow.
Side effects
- Invalid or malformed EIP-712 domain object returns a 400 error
- Wallet address not found or invalid format causes validation failure
- Malformed EIP-712 message structure results in a parsing error
- Payment not provided or insufficient USDC balance returns 402 Payment Required
- Rate limiting or upstream node errors may cause transient 5xx failures
