AI-assisted Cardano transaction building using MeshTxBuilder from @meshsdk/transaction.
npm install @meshsdk/transaction
# or
npm install @meshsdk/core # includes transaction + wallet + provider
| Task | Method Chain |
|---|---|
| Send ADA | txIn() -> txOut() -> changeAddress() -> complete() |
| Mint tokens (Plutus) | mintPlutusScriptV2() -> mint() -> mintingScript() -> mintRedeemerValue() -> ... |
| Mint tokens (Native) | mint() -> mintingScript() -> ... |
| Script spending | spendingPlutusScriptV2() -> txIn() -> txInScript() -> txInDatumValue() -> txInRedeemerValue() -> ... |
| Stake delegation | delegateStakeCertificate(rewardAddress, poolId) |
| Withdraw rewards | withdrawal(rewardAddress, coin) -> withdrawalScript() -> withdrawalRedeemerValue() |
| Governance vote | vote(voter, govActionId, votingProcedure) |
| DRep registration | drepRegistrationCertificate(drepId, anchor?, deposit?) |
import { MeshTxBuilder } from '@meshsdk/transaction';
const txBuilder = new MeshTxBuilder({
fetcher?: IFetcher, // For querying UTxOs (e.g., BlockfrostProvider)
submitter?: ISubmitter, // For submitting transactions
evaluator?: IEvaluator, // For script execution cost estimation
serializer?: IMeshTxSerializer, // Custom serializer
selector?: IInputSelector, // Custom coin selection
isHydra?: boolean, // Hydra L2 mode (zero fees)
params?: Partial<Protocol>, // Custom protocol parameters
verbose?: boolean, // Enable logging
});
| Method | Async | Balanced | Use Case |
|---|---|---|---|
complete() | Yes | Yes | Production - auto coin selection, fee calculation |
completeSync() | No | No | Testing - requires manual inputs/fee |
completeUnbalanced() | No | No | Partial build for inspection |
completeSigning() | No | N/A | Add signatures after complete() |
All methods return this for chaining:
txBuilder
.txIn(hash, index)
.txOut(address, amount)
.changeAddress(addr)
.complete();
