Use TypeScript SDK (Orchestrator)
Purpose
Orchestrates @aptos-labs/ts-sdk integration for Aptos dApps. For specific tasks, route to the appropriate granular skill. For composite tasks (e.g., "build me a fullstack dApp"), follow the workflow below.
Core Rules
-
ALWAYS use @aptos-labs/ts-sdk (the current official SDK, NOT the deprecated aptos package)
-
NEVER hardcode private keys in source code or frontend bundles
-
NEVER expose private keys in client-side code or logs
-
NEVER store private keys in environment variables accessible to the browser (use VITE_ prefix only for public config)
-
ALWAYS load private keys from environment variables in server-side scripts only, using process.env
Important: Boilerplate Template
If the project was scaffolded with npx create-aptos-dapp (boilerplate template), wallet adapter and SDK setup are already done. Before writing new code, check what already exists:
-
frontend/components/WalletProvider.tsx — wallet adapter setup with auto-connect
-
frontend/constants.ts — NETWORK , MODULE_ADDRESS , APTOS_API_KEY from env vars
-
frontend/entry-functions/ — existing entry function patterns (follow these for new ones)
-
frontend/view-functions/ — existing view function patterns (follow these for new ones)
Do NOT recreate wallet provider, client setup, or constants if they already exist. Instead, follow the existing patterns to add new entry/view functions for your Move contracts.
Skill Routing
Route to the appropriate granular skill based on the task:
Task Skill
Set up Aptos client / configure network ts-sdk-client
Create accounts/signers (server-side) ts-sdk-account
Parse, format, or derive addresses ts-sdk-address
Build, sign, submit, simulate transactions ts-sdk-transactions
Read on-chain data (view, balances, resources) ts-sdk-view-and-query
Map Move types to TypeScript types ts-sdk-types
Connect wallet in React frontend ts-sdk-wallet-adapter
Fullstack dApp Workflow
When building a complete frontend integration:
-
Set up client → read ts-sdk-client
-
Create view function wrappers → read ts-sdk-view-and-query
-
Create entry function payloads → read ts-sdk-transactions
-
Wire up wallet connection → read ts-sdk-wallet-adapter
-
Handle types correctly → read ts-sdk-types (as needed)
File Organization Pattern
src/ lib/ aptos.ts # Singleton Aptos client + MODULE_ADDRESS view-functions/ getCount.ts # One file per view function getListing.ts entry-functions/ increment.ts # One file per entry function createListing.ts hooks/ useCounter.ts # React hooks wrapping view functions useListing.ts components/ WalletProvider.tsx # AptosWalletAdapterProvider wrapper IncrementButton.tsx # Components calling entry functions
Error Handling Pattern
async function submitTransaction( aptos: Aptos, signer: Account, payload: InputGenerateTransactionPayloadData ): Promise<string> { try { const transaction = await aptos.transaction.build.simple({ sender: signer.accountAddress, data: payload });
const pendingTx = await aptos.signAndSubmitTransaction({
signer,
transaction
});
const committed = await aptos.waitForTransaction({
transactionHash: pendingTx.hash
});
if (!committed.success) {
throw new Error(`Transaction failed: ${committed.vm_status}`);
}
return pendingTx.hash;
} catch (error) {
if (error instanceof Error) {
if (error.message.includes("RESOURCE_NOT_FOUND")) {
throw new Error("Resource does not exist at the specified address");
}
if (error.message.includes("MODULE_NOT_FOUND")) {
throw new Error("Contract is not deployed at the specified address");
}
if (error.message.includes("ABORTED")) {
const match = error.message.match(/code: (\d+)/);
const code = match ? match[1] : "unknown";
throw new Error(Contract error (code ${code}));
}
}
throw error;
}
}
Edge Cases
Scenario Check Action
Resource not found error.message.includes("RESOURCE_NOT_FOUND")
Return default value or null
Module not deployed error.message.includes("MODULE_NOT_FOUND")
Show "contract not deployed" message
Function not found error.message.includes("FUNCTION_NOT_FOUND")
Check function name and module address
Move abort error.message.includes("ABORTED")
Parse abort code, map to user-friendly error
Out of gas error.message.includes("OUT_OF_GAS")
Increase maxGasAmount and retry
Sequence number error error.message.includes("SEQUENCE_NUMBER")
Retry after fetching fresh sequence number
Network timeout error.message.includes("timeout")
Retry with exponential backoff
Account does not exist error.message.includes("ACCOUNT_NOT_FOUND")
Fund account or prompt user to create one
Insufficient balance error.message.includes("INSUFFICIENT_BALANCE")
Show balance and required amount
User rejected in wallet Wallet-specific rejection error Show "transaction cancelled" message
Anti-patterns
-
NEVER use the deprecated aptos npm package — use @aptos-labs/ts-sdk
-
NEVER skip waitForTransaction after submitting — transaction may not be committed yet
-
NEVER hardcode module addresses — use environment variables (VITE_MODULE_ADDRESS )
-
NEVER create multiple Aptos client instances — create one singleton and share it
-
NEVER use Account.generate() in frontend code for real users — use wallet adapter
-
NEVER use scriptComposer — removed in v6.0; use separate transactions instead
-
NEVER use getAccountCoinAmount or getAccountAPTAmount — deprecated; use getBalance()
SDK Version Notes
AIP-80 Private Key Format (v2.0+)
Ed25519 and Secp256k1 private keys now use an AIP-80 prefixed format when serialized with toString() :
const key = new Ed25519PrivateKey("0x..."); key.toString(); // Returns AIP-80 prefixed format, NOT raw hex
Fungible Asset Transfers (v1.39+)
await aptos.transferFungibleAssetBetweenStores({ sender: account, fungibleAssetMetadataAddress: metadataAddr, senderStoreAddress: fromStore, recipientStoreAddress: toStore, amount: 1000n });
Account Abstraction (v1.34+, AIP-104)
// Check if AA is enabled for an account
const isEnabled = await aptos.abstraction.isAccountAbstractionEnabled({
accountAddress: "0x...",
authenticationFunction: ${MODULE_ADDRESS}::auth::authenticate
});
// Enable AA on an account
const enableTxn = await aptos.abstraction.enableAccountAbstractionTransaction({
accountAddress: account.accountAddress,
authenticationFunction: ${MODULE_ADDRESS}::auth::authenticate
});
// Use AbstractedAccount for signing with custom auth logic import { AbstractedAccount } from "@aptos-labs/ts-sdk";
