Wiki route

This entry sits under AI Agent payment protocols overview · a 7-protocol survey. Read it against payments index for peer / contrast context and systems index for the broader system / regulatory boundary.

Key facts

  • A 2024 proposal · implemented in 2025 major wallets
  • Core RPC: wallet_grantPermissions
  • Permission types are extensible: native-token-recurring-allowance / erc20-token-transfer / contract-call / nft-transfer
  • The signer can be an EOA / passkey / AI agent service key
  • Analogy to OAuth 2.0 : not “handing the app your password” but “handing the app a scope-limited access token”

Mechanism / How it works

Core RPC: wallet_grantPermissions

{
  "chainId": "0x2105",
  "expiry": 1735689600,
  "signer": { "type": "key", "data": { "id": "0xagent..." } },
  "permissions": [
    {
      "type": "native-token-recurring-allowance",
      "data": { "amount": "0x...", "period": 86400 }
    },
    {
      "type": "erc20-token-transfer",
      "data": { "token": "0xUSDC...", "limit": "10000000", "to": "0xmerchant..." }
    }
  ]
}

Permission types (extensible):

  • native-token-recurring-allowance — periodic ETH/SOL limit
  • erc20-token-transfer — restricted token + limit + recipient
  • contract-call — restricted contract + selector
  • nft-transfer — restricted collection + tokenId range
  • Any dapp can define a custom permission type

**Coordination with 4337 / 7702 **:

Signer flexibility: the signer can be another EOA, a passkey, or an AI agent’s service key — any entity capable of signing can be chosen. This means an AI agent having a “scope-limited child account” is supported at the protocol level.

Origin & evolution

The origin of the 7715 draft lies in coordination discussions between the MetaMask Snaps team and the Coinbase Smart Wallet team in 2024 年 — both had independently implemented session keys, but the formats could not interoperate. Referencing the OAuth 2.0 scope model · it was defined as a unified permission-request protocol.

It was implemented successively on MetaMask, Coinbase Smart Wallet, and Safe in 2025 年. Around the same time it combined with ERC-4337 / 7702 to form the complete “AA + Permissions” stack, and alongside AP2 / x402 it is regarded as important infrastructure for the AI agent economy.
