Pact policies and completion conditions

Every pact submission includes two top-level JSON arrays:

{
  "completion_conditions": [ ... ],
  "policies": [ ... ]
}

Completion conditions define when the pact automatically ends — time elapsed, transactions executed, or amount spent. The pact is revoked as soon as any one condition is met. Policies define what the agent is allowed to do while the pact is active — which chains, tokens, contracts, or message types are permitted, and what limits apply.

Completion conditions

Completion conditions determine when a pact automatically ends. At least one is required. The pact completes when any condition is satisfied, after which access is revoked immediately. Types cannot be duplicated within a pact.

Type	Threshold	Description
`tx_count`	string (integer)	Complete after N successful transactions — e.g. `"1"` for a one-time operation
`amount_spent`	string (decimal)	Complete after cumulative token amount reaches this — e.g. `"1000"` for 1000 USDC
`amount_spent_usd`	string (decimal)	Complete after cumulative USD spend reaches this — e.g. `"500"`
`time_elapsed`	string (seconds)	Complete after N seconds from pact activation — e.g. `"2592000"` for 30 days

[
  {"type": "tx_count", "threshold": "12"},
  {"type": "time_elapsed", "threshold": "7776000"}
]

This pact ends after 12 transactions or 90 days, whichever comes first.

Policies

Policies are the rules that constrain what an agent can do within a pact. Every operation the runtime submits is evaluated against the policies you define.

How the engine works

The policy engine evaluates every operation against all applicable policies and outputs one of three decisions: allow, require_approval, or deny.

Evaluation order (within a policy)

Match when conditions — if not matched, the policy is skipped
Check deny_if — if hit, deny immediately
Check review_if / always_review — if hit, pause for owner approval
Otherwise, allow

Default-deny semantics

Pact-level policies use fail-closed semantics: if the operation does not match any policy’s when conditions, it is automatically denied. Every operation the agent needs to perform must be explicitly covered by a policy.

Final decision

When multiple policies apply:

Any deny → deny
No deny, but any review triggered → require_approval
Otherwise → allow

Policy structure

Each policy in the policies array has this shape:

{
  "name": "<human-readable name>",
  "type": "transfer | contract_call | message_sign",
  "rules": {
    "effect": "allow",
    "when": { ... },
    "deny_if": { ... },
    "review_if": { ... },
    "always_review": true | false
  }
}

Field	Required	Description
`name`	Yes	Human-readable label for this policy
`type`	Yes	Operation type: `transfer`, `contract_call`, or `message_sign`
`rules.effect`	Yes	Always `"allow"` for pact-level policies
`rules.when`	Yes (unless `always_review: true`)	Allowlist conditions — which chains, tokens, or contracts are permitted
`rules.deny_if`	No	Hard-block conditions — operations that exceed these limits are denied
`rules.review_if`	No	Soft-block conditions — operations exceeding these thresholds pause for owner approval
`rules.always_review`	No	When `true`, every matched operation requires owner approval

Constraints:

deny_if takes priority over review_if / always_review
deny effect policies cannot have review_if or always_review
allow + review_if requires a non-empty when
allow requires either a non-empty when or always_review: true

Transfer policies

Use "type": "transfer" to control token transfers.

`when` — allowlist conditions

All fields are AND conditions. All specified fields must match.

Field	Type	Description
`chain_in`	`string[]`	Restrict to specific chains, e.g. `["BASE_ETH", "ETH"]`
`token_in`	`ChainTokenRef[]`	Restrict to specific tokens — `[{"chain_id": "BASE_ETH", "token_id": "BASE_USDC"}]`
`destination_address_in`	`ChainAddressRef[]`	Restrict to specific destination addresses — `[{"chain_id": "BASE_ETH", "address": "0x..."}]`

`deny_if` — hard-block limits

Field	Type	Description
`amount_gt`	string (decimal)	Deny if a single transfer’s token amount exceeds this
`amount_usd_gt`	string (decimal)	Deny if a single transfer’s USD value exceeds this
`usage_limits.rolling_1h`	object	Rolling 1-hour window limits
`usage_limits.rolling_24h`	object	Rolling 24-hour window limits
`usage_limits.rolling_7d`	object	Rolling 7-day window limits
`usage_limits.rolling_30d`	object	Rolling 30-day window limits

Each rolling window supports: amount_gt, amount_usd_gt, tx_count_gt.

`review_if` — approval thresholds

Supports the same fields as when (chain_in, token_in, destination_address_in), plus:

Field	Type	Description
`amount_gt`	string (decimal)	Require approval if token amount exceeds this
`amount_usd_gt`	string (decimal)	Require approval if USD value exceeds this

Contract call policies

Use "type": "contract_call" to control smart contract interactions. EVM and Solana use different target fields.

`when` — allowlist conditions (EVM)

Field	Type	Description
`chain_in`	`string[]`	Restrict to specific chains
`target_in`	`ContractTargetRef[]`	Allowlist by contract address and optionally function selector — `[{"chain_id": "SETH", "contract_addr": "0x...", "function_id": "0x38ed1739"}]`. Omit `function_id` to allow all functions on the contract.
`params_match`	`ParamMatchRule[]`	Match on decoded calldata parameters (EVM only — requires `function_abis`)

`when` — allowlist conditions (Solana)

Field	Type	Description
`chain_in`	`string[]`	Restrict to specific chains
`program_in`	`ProgramRef[]`	Allow if the transaction involves any of the listed programs
`program_all_in`	`ProgramRef[]`	Allow only if the transaction involves all of the listed programs

`params_match` rule

Used to match on decoded function parameters. Requires function_abis to be set.

Field	Type	Description
`param_name`	string	Parameter name as defined in the ABI
`op`	string	`eq`, `neq`, `in`, `not_in`, `gt`, `gte`, `lt`, `lte`
`value`	any	Value to compare against

params_match is only supported on EVM chains. Multiple rules are AND conditions.

`function_abis`

Required when using params_match. Provide the ABI fragment for each function selector you reference:

"function_abis": [
  {
    "type": "function",
    "selector": "0x38ed1739",
    "inputs": [
      {"name": "amountIn", "type": "uint256"},
      {"name": "recipient", "type": "address"}
    ]
  }
]

`deny_if` — hard-block limits

Field	Type	Description
`amount_gt`	string	Deny if the operation’s native value exceeds this
`amount_usd_gt`	string	Deny if the USD value exceeds this
`usage_limits`	object	Same rolling window structure as transfer (`rolling_1h`, `rolling_24h`, `rolling_7d`, `rolling_30d`), each supporting `amount_gt`, `amount_usd_gt`, `tx_count_gt`

`review_if` — approval thresholds

Supports the same fields as when (chain_in, target_in, program_in, params_match), plus amount_gt and amount_usd_gt.

      ]
    }
  }
}

Message sign policies

Use "type": "message_sign" to control EIP-712 typed-data signing. There are no amount_gt / amount_usd_gt fields — rate limits use request_count_gt instead.

`when` — allowlist conditions

Field	Type	Description
`chain_in`	`string[]`	Restrict to specific chains
`primary_type_in`	`string[]`	Match on the EIP-712 `primaryType` field, e.g. `["PermitSingle", "PermitBatch"]`
`source_address_in`	`ChainAddressRef[]`	Restrict to specific signing addresses. EVM: case-insensitive. Solana: case-sensitive.
`domain_match`	`MatchRule[]`	Match on EIP-712 `domain` fields
`message_match`	`MatchRule[]`	Match on EIP-712 `message` fields

All when fields are AND conditions.

Path syntax for `domain_match` and `message_match`

Use dot notation to address nested fields:

Syntax	Meaning	Example
`.`	Nested field	`details.spender`
`[N]`	Array index (0-based)	`path[0].tokenIn`
`*`	All array elements	`items.*.token`
`.length`	Array length	`transfers.length`

Wildcard semantics — for multi-value paths like items.*.token:

eq, in, gt, gte, lt, lte: matches if any element satisfies the condition
neq, not_in: matches only if all elements satisfy the condition

Supported operators: eq, neq, in, not_in, gt, gte, lt, lte

Path resolution failures

When a path cannot be resolved, the rule does not match:

Situation	Result
Intermediate field missing or `null`	No match
`*` applied to a non-array	No match
`[N]` index out of bounds	No match
`.length` applied to a non-array	No match
Empty array + `eq`, `in`, `gt`, `gte`, `lt`, `lte`	`false` (no match)
Empty array + `neq`, `not_in`	`true` (matches)

`deny_if` — rate limits

Field	Type	Description
`usage_limits.rolling_1h.request_count_gt`	integer	Deny if signing requests in the past hour exceed this
`usage_limits.rolling_24h.request_count_gt`	integer	Deny if signing requests in the past 24h exceed this
`usage_limits.rolling_7d.request_count_gt`	integer	Deny if signing requests in the past 7 days exceed this
`usage_limits.rolling_30d.request_count_gt`	integer	Deny if signing requests in the past 30 days exceed this

`review_if` — approval thresholds

Supports the same fields as when (chain_in, primary_type_in, source_address_in, domain_match, message_match).

Chain ID validation

For EVM chains, the engine checks that the request chain_id matches domain.chainId in the typed data. A mismatch results in an immediate deny with reason eip712_domain_chain_id_mismatch.

      ]
    }
  }
}

Amount units

amount_gt, amount_spent, and related fields use the token’s transfer unit — the same unit passed when submitting a transfer:

"1.5" for USDC means 1.5 USDC (not 1,500,000 micro-USDC)
"0.01" for ETH means 0.01 ETH (not wei)

USD-based conditions (amount_usd_gt, amount_spent_usd) only apply to tokens with available price data. For tokens without price data, use token-denominated limits (amount_gt, amount_spent) instead.
