Draft TIP for protocol-native parent-child account linking. Enables the headless agent wallet flow: start with a private key, onramp, do things, later link to a passkey-based parent that can pull funds and revoke access keys.
Key design decisions:
SubAccountAuthorizationwith nonce + deadline (replay-safe)pullFundsgoes through standard TIP-20/TIP-403 transfer pathsystemRevokeKeyhook — root-key migration deferred to a future TIPRelated: TIP-1011 (enhanced access key permissions), TIP-1022 (virtual addresses)
