Approvals & revoke

Every token approval a wallet still has live on Robinhood Chain, newest first: who can spend what, how risky that spender looks, and a revoke transaction Toll has checked.

Read from the chain: ERC-20 approvals, NFT approval-for-all and Permit2 allowances, the current amount of each.
High risk: unlimited to a plain wallet, or to code nobody can name. Each revoke is run through the pre-sign check first.
Agents: the same list is the MCP tool wallet_approvals and GET /api/approvals/{wallet}.
