WebAssembly bindings for the keetanetwork-client crate.

Build the package with wasm-pack build --target web, then drive it from the browser.

Conventions

• Amounts are decimal strings ("1000"), never JS number.
• Cryptographic bytes (sign/verify/encrypt/decrypt) are Uint8Array; hashes and keys are hex strings.
• Errors are JS Error objects carrying a stable error.code for programmatic handling (e.g. INVALID_PERMISSION_FLAG).

Example

import init, { KeetaClient, UserClient, Account, TransmitOptions } from './pkg/keetanetwork_client_wasm.js';

// Instantiate the wasm module once.
await init();

// Named network (resolves representatives + id), or `new KeetaClient(url)`
// plus `.withNetwork(id)` for a custom endpoint.
const client = KeetaClient.forNetwork('test');

// Derive an account (algorithm defaults to ecdsa_secp256k1).
const me = Account.fromSeed(Account.generateSeed(), 0);
const token = Account.fromAddress('keeta_...token...');
const to = Account.fromAddress('keeta_...recipient...');

// High-level signed write: send(to, amount, token).
const user = UserClient.fromClient(client, me);
await user.send(to, '1000', token);

// Or assemble a multi-operation block and transmit it as one round.
const builder = user.initBuilder();
builder.send(to, '250', token);
await user.transmit(await builder.build(), new TransmitOptions());

// Sign / verify arbitrary bytes.
const message = new TextEncoder().encode('hello');
const signature = me.sign(message);
const ok = me.verify(message, signature); // true

try {
  await user.send(to, 'not-a-number', token);
} catch (error) {
  console.error(error.code, error.message); // INVALID_AMOUNT ...
}
