Approve spender to use tokens

balanceOf(trit27 account) → trit27

Get account balance in ternary format

ternaryAdd(trit27 a, trit27 b) → trit27

The TritToken smart contract demonstrates our ternary-based contract system, featuring methods for token transfers, approvals, and ternary arithmetic operations.

7.1 Ternary Virtual Machine

Core Implementation

Built with our Next.js/TypeScript stack:

typescript
1// Virtual Machine types and interfaces
2interface TritVM {
3 // Instruction set
4 type Instruction = {
5 opcode: TritOpCode;
6 operands: TritValue[];
7 };
8
9 // Memory model
10 interface MemoryState {
11 stack: TritValue[];
12 storage: Map<TritAddress, TritValue>;
13 memory: TritValue[];
14 }
15}

7.2 Contract Programming Model

TypeScript Integration

Leveraging our monorepo structure:

typescript
1// Smart contract interface
2interface TritContract {
3 // Contract state
4 interface State {
5 balance: TritValue;
6 storage: Map<TritAddress, TritValue>;
7 owner: TritAddress;
8 }
9
10 // Contract methods
11 interface Methods {
12 execute(method: string, args: TritValue[]): Promise<TritValue>;
13 view(method: string, args: TritValue[]): Promise<TritValue>;
14 }
15}
16
17// Contract development with Next.js
18export default function ContractDevelopment() {
19 return (
20 <StyledContractDev>
21 <Editor
22 language="typescript"
23 theme={tritTheme}
24 onChange={handleCodeChange}
25 />
26 <Compiler
27 code={sourceCode}
28 onCompile={handleCompilation}
29 />
30 <Deployer
31 bytecode={compiledCode}
32 onDeploy={handleDeployment}
33 />
34 </StyledContractDev>
35 );
36}
37
38// Contract testing framework
39class ContractTest {
40 async testMethod(
41 contract: TritContract,
42 method: string,
43 args: TritValue[]
44 ): Promise<TestResult> {
45 try {
46 const result = await contract.execute(method, args);
47 return { success: true, result };
48 } catch (error) {
49 return { success: false, error };
50 }
51 }
52}
Our contract development environment is fully integrated with TypeScript for type safety and Next.js for optimal development experience.

7.3 Oracle Integration

Implementation

Built on our React/TypeScript foundation:

typescript
1interface TritOracle {
2 // Oracle types
3 interface DataFeed {
4 source: string;
5 updateInterval: number;
6 value: TritValue;
7 signature: TritSignature;
8 }
9
10 // Oracle network
11 interface OracleNetwork {
12 nodes: OracleNode[];
13 aggregator: DataAggregator;
14 verifier: SignatureVerifier;
15 }
16}
17
18// Oracle implementation
19class DecentralizedOracle implements TritOracle {
20 private readonly network: OracleNetwork;
21
22 // Data fetching with Next.js API routes
23 async fetchData(
24 source: string
25 ): Promise<DataFeed> {
26 const response = await fetch('/api/oracle/fetch', {
27 method: 'POST',
28 body: JSON.stringify({ source })
29 });
30 return response.json();
31 }
32
33 // Data verification
34 async verifyData(
35 feed: DataFeed
36 ): Promise<boolean> {
37 return this.network.verifier.verify(feed);
38 }
39}
40
41// React component for oracle monitoring
42const OracleMonitor: React.FC<{
43 oracle: DecentralizedOracle;
44 feeds: DataFeed[];
45}> = ({ oracle, feeds }) => {
46 return (
47 <StyledOracleView>
48 <NetworkStatus network={oracle.network} />
49 <FeedList feeds={feeds} />
50 <VerificationStatus oracle={oracle} />
51 </StyledOracleView>
52 );
53};

Cross-Chain Communication

typescript
1interface CrossChainBridge {
2 // Bridge operations
3 async function sendMessage(
4 targetChain: ChainId,
5 message: TritValue
6 ): Promise<TxHash>;
7
8 async function receiveMessage(
9 sourceChain: ChainId,
10 proof: MessageProof
11 ): Promise<boolean>;
12}
13
14// Bridge implementation with Next.js
15export default function handler(
16 req: NextApiRequest,
17 res: NextApiResponse<BridgeResponse>
18) {
19 const { targetChain, message } = req.body;
20
21 try {
22 const result = await bridge.sendMessage(targetChain, message);
23 res.status(200).json({ result });
24 } catch (error) {
25 res.status(400).json({ error: error.message });
26 }
27}
