| [`FundingPolicy.fromRpc`](/tempo/reference/FundingPolicy/fromRpc) | Converts an RPC policy authorization to its domain representation. |
| [`FundingPolicy.fromTuple`](/tempo/reference/FundingPolicy/fromTuple) | Decodes a canonical policy authorization tuple. |
| [`FundingPolicy.hash`](/tempo/reference/FundingPolicy/hash) | Computes the protocol's domain-separated commitment to rules. |
| [`FundingPolicy.toRoutes`](/tempo/reference/FundingPolicy/toRoutes) | Converts a token map to canonical ABI routes, without reordering sources. |
| [`FundingPolicy.toRpc`](/tempo/reference/FundingPolicy/toRpc) | Converts a policy authorization to its RPC representation. |
| [`FundingPolicy.toTuple`](/tempo/reference/FundingPolicy/toTuple) | Encodes an existing policy ID or an inline policy as an RLP tuple. |

## Errors

| Name                | Description                         |
