Versioned builds live under /sdk/<version>/. Current: 0.3.3. Latest alias: latest

Quick embed (SRI pinned):

        integrity="sha256-9F4XbjSBgRo3RaNWFJd/g96U4iv5n0GFJj/JgFaUveQ="

<script>
(async () => {
  const bc = await BlazeConnect.ready({ timeoutMs: 3000 });
  if (!bc.isInstalled) return;
  bc.on('accountChanged', ({ publicKey }) => console.log('accountChanged', publicKey));
  const { publicKey } = await bc.connect();
  console.log(publicKey);
})();
</script>
      

ESM (SDK v0.2.0+):

<script type="module">
import { BlazeClient } from 'https://cdn.blazedefi.com/sdk/0.3.3/js/index.js';
const client = new BlazeClient({ baseUrl: 'https://connect.blazedefi.com' });
console.log(await client.getHealth());
</script>

Getting started

TypeScript (Node/Vite):

// install
npm install blaze-sdk

// usage
import { BlazeClient } from 'blaze-sdk';
const client = new BlazeClient({ baseUrl: 'https://connect.blazedefi.com' });
console.log(await client.getHealth());
      

Plain JS via CDN (ESM):

<script type="module">
  import { BlazeClient } from 'https://cdn.blazedefi.com/sdk/latest/js/index.js';
  const client = new BlazeClient({ baseUrl: 'https://connect.blazedefi.com' });
  console.log(await client.getLatestBlock());
</script>
      

Wallet provider (IIFE global): include once, then use BlazeConnect.

<script src="https://cdn.blazedefi.com/sdk/latest/wallet/blaze-connect.iife.js" crossorigin="anonymous"></script>
<script>
(async () => {
  const bc = await BlazeConnect.ready({ timeoutMs: 3000 });
  if (!bc.isInstalled) return;
  const { publicKey } = await bc.connect();
  console.log('pk', publicKey);
})();
</script>
      

Common tasks

List recent blocks with auto-pagination

const page = await client.listBlocks({ limit: 5 });
for await (const b of page.asIterable()) {
  console.log(b.height, b.hash);
}
      

Estimate fees and submit

const instructions = [
  { type: 'transfer', from, to, amount: '100000000', data: { token_address } },
];
const est = await client.estimateFees(instructions);
// sign transaction outside SDK (ed25519 over sha3-256) then submit
const { hash } = await client.submitTransaction(signedTx);
await client.waitForConfirmed(hash, { minConfirmations: 1 });
      

Quote a swap

const q = await client.quoteSwap(poolAddr, blazeAddr, otherTokenAddr, '100000000');
console.log('min received', q.minimum_received);
      

Amount helpers

toBaseUnits('1.23', 8)        // '123000000'
fromBaseUnits('123000000', 8) // '1.23'

Essentials

• API base: https://connect.blazedefi.com
• Amounts: base units as strings (uint64); native token has 8 decimals
• Errors: non-2xx → JSON { error, message, details? }; HTTP status is authoritative
• Environments: modern browsers (ESM) and Node ≥ 18 (global fetch)

Versioning & CDN cache

• Versioned paths are immutable: /sdk/<version>/...
• latest alias points to the most recent release and is short-cached
• SRI snippet above pins the exact file integrity for extra safety
