feat(platform)!: allow contract-bound authentication keys - #4780
Conversation
Protocol 14 lets an identity register an AUTHENTICATION key whose existing contractBounds (singleContract or documentType) restrict what it may sign. No wire format changes: only which keys may carry bounds and what the bounds mean for signing. Consensus (protocol 14 tables only): - contract-bounds validation v2 admits non-MASTER authentication keys on any existing contract and document type; encryption and decryption keep v1. - identity-signature validation v1 refuses a bound authentication key on any non-Batch transition (ContractBoundedKeyNonBatchError, unpaid). - batch advanced-structure v1 requires every member to be inside the signing key's bounds (ContractBoundedKeyOutOfBoundsError, paid, nonce bumped). Token operations are contract-wide and never covered by a document-type bound. - identity create (asset lock, addresses, shielded pool) state v1 validates key bounds at creation; identity update state v1 retains the contract lookup fees in the caller's context. Drive (DRIVE_VERSION_V9 / identity methods V2): - contract-info indexing v1 stores bound authentication keys under a new AUTHENTICATION purpose subtree per bound group, with the current-key alias inside that subtree; refresh v1 maintains it on revocation (untrusted, so revoking an older key never repoints the alias at it). - apply_batch_low_level_drive_operations v1 coalesces alias writes per slot across a whole identity update: an insertion beats a refresh and the highest key id wins. - disable_identity_keys v1 estimates fees from the stored keys so a bound key's reference refreshes are priced. - all-keys listings of an AUTHENTICATION purpose subtree skip the alias. SDK signing helpers refuse to sign a transition the bounds do not cover. The consensus and Drive plumbing is carried over from #4613, without its scope type, permission mask and expiry.

…stimation Indexing v1 and refresh v1 estimated each bound contract lookup with a fixed 100-byte stand-in while the apply path billed the real fetch, so a cold user contract could execute above its estimate. Both v1 paths now fetch the contract in estimation mode as well and bill the same PreCalculatedFeeResult the apply path bills; v0 keeps the stand-in. The regression compares the contract lookup fees of the estimated and applied revocation operations for two cold user contracts, bound at contract and at document-type level, and checks registration and revocation estimates cover execution.

The batch-level alias coalescer recognized any empty-key sibling reference write. Encryption and decryption bounds keep their frozen v0 layout, with the current-key alias one level up at the keys level, and that layout must not pick up new batch semantics from the authentication change. Restrict the coalescer to the AUTHENTICATION contract-info purpose subtree (Identities / identity / IdentityContractInfo / group / ContractInfoKeysKey / AUTHENTICATION) and pin the boundary with unit tests: authentication slots coalesce per group to the insertion naming the highest key id, keys-level and other-purpose aliases pass through untouched, duplicate refreshes collapse, key-id entries are left alone. Also drop the extra blank lines in the identity-create-from-addresses state v1 trait body. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Issue being fixed or feature implemented
Applications need a signing key limited to one contract. Protocol 14 lets an identity register an AUTHENTICATION key whose existing
contractBounds(singleContractordocumentType) restrict what it may sign. This replaces the approach in #4613, which introduced a newScopedbounds variant with a permission mask, multi-contract scopes and expiry. The Drive and consensus plumbing from that PR is carried over; the scope type, its encoding and validation, the permission bits, expiry, the decode-time activation gate, the raised decode budgets, the shielded sighash v1 and the wallet FFI rejection code are gone. No wire format changes, so existing clients and wallets already decode these keys and the dependent SDK PR shrinks to key selection.Decisions taken in this PR: any contract may be bound (no contract opt-in flag, unlike encryption bounds); bound authentication keys use the multiple-with-current-pointer storage rule; a document-type bound never covers token operations; MASTER keys cannot be bound.
What was done?
Consensus, protocol 14 tables only:
ContractBoundedKeyNonBatchError, unpaid.ContractBoundedKeyOutOfBoundsError, a paid failure with the nonce bumped. Token operations are contract-wide and never covered by a document-type bound.ContractBounds::allows_batched_transitionis the single membership rule, used by consensus and by the SDK signing helpers, which refuse to sign a transition the bounds do not cover.Drive (
DRIVE_VERSION_V9, identity methods V2):apply_batch_low_level_drive_operationsv1 coalesces alias writes per slot across a whole identity update: an insertion beats a refresh, the highest key id wins, duplicate refreshes collapse. This is what makes registering a replacement and revoking the current key in one transition safe under batching consistency verification.disable_identity_keysv1 estimates fees from the stored keys so a bound key's reference refreshes are priced; v0 estimated with a boundless stand-in.GroveDB layout: before and after
Contract-bound key references live under each identity's
ContractInfosubtree, one group per bound: the contract id, or the contract id concatenated with the document type name.Before (protocol 13): only ENCRYPTION and DECRYPTION keys may carry bounds; an AUTHENTICATION key with bounds is rejected at indexing.
After (protocol 14): legacy groups are written exactly as before. A bound authentication key
Kadds an AUTHENTICATION purpose subtree to its one group:Why the layout changes at all: consensus and clients ask "which key does identity I use for contract C" per contract, so bound authentication keys reuse the per-group layout the legacy bounds already have. The purpose subtree is new because indexing v0 rejected authentication keys with bounds. The current-key pointer sits inside the purpose subtree, next to the key ids it names, so current-key fetches and
getIdentitiesContractKeysresolve; the legacy pointer one level up is left untouched.How Has This Been Tested?
SignatureErrordiscriminants.cargo check --workspace --tests, clippy with denied warnings on dpp, drive and drive-abci, rustfmt.Breaking Changes
Activation requires protocol 14. Two
SignatureErrorvariants and codes 20013 and 20014 are appended. Bound authentication keys have no per-operation permissions, spending limits or expiry: a bound key is full authority over its contract until disabled through a master-key identity update (seedocs/protocol/contract-bound-authentication-keys.md).Checklist:
