Provider
Defined in: ootle/src/provider.ts:22
A Provider reads chain state and submits transactions. It has no signing capability. The canonical implementation is IndexerProvider, which talks to the indexer REST API.
Methods
Section titled “Methods”fetchSubstates()
Section titled “fetchSubstates()”fetchSubstates(
requests):Promise<GetSubstatesResponse>
Defined in: ootle/src/provider.ts:49
Fetches multiple substates by ID in a single request.
Parameters
Section titled “Parameters”requests
Section titled “requests”string[]
Returns
Section titled “Returns”Promise<GetSubstatesResponse>
getCurrentEpoch()
Section titled “getCurrentEpoch()”getCurrentEpoch():
Promise<number>
Defined in: ootle/src/provider.ts:34
Returns the epoch the network is currently on.
Every transaction carries a mandatory max_epoch, capped at
MAX_TRANSACTION_VALIDITY_EPOCHS past this value, so a builder needs the chain tip
before it can be constructed: TransactionBuilder.new(network, await provider.getCurrentEpoch() + 10).
Returns
Section titled “Returns”Promise<number>
getStealthUtxo()
Section titled “getStealthUtxo()”getStealthUtxo(
resourceAddress,commitment):Promise<IndexerGetSubstateResponse|null>
Defined in: ootle/src/provider.ts:46
Fetches a stealth UTXO substate by resource address + 32-byte commitment.
The provider owns the utxo_{resourceHex}_{commitmentHex} id format; callers pass
the resource and commitment and never string the id themselves. Returns null when
the UTXO does not exist (already spent / never created), instead of throwing.
Parameters
Section titled “Parameters”resourceAddress
Section titled “resourceAddress”string
commitment
Section titled “commitment”Uint8Array
Returns
Section titled “Returns”Promise<IndexerGetSubstateResponse | null>
getSubstate()
Section titled “getSubstate()”getSubstate(
substateId,version?):Promise<IndexerGetSubstateResponse>
Defined in: ootle/src/provider.ts:37
