Registration

Registration instructions can be created either via SDK or API, both methods are equivalent. To register a domain you will have to specify the following:

• Domain names
• Space (between 1kb and 10kb)
• The public key of the buyer

Domain names can be registered with the following tokens: USDC, USDT, wSOL, FIDA, mSOL, BONK and BAT.

Note: The registration instruction does not support native SOL but wrapped SOL

SDK

Unregistered domains can be registered using the SDK @bonfida/spl-name-service with the following instructions:

import { registerDomainName } from "@bonfida/spl-name-service";

const name = "bonfida"; // We want to register bonfida.sol
const space = 1 * 1_000; // We want a 1kB sized domain (max 10kB)

const buyer = new PublicKey("..."); // Publickey of the buyer
const buyerTokenAccount = new PublicKey("..."); // Publickey of the token account of the buyer (USDC)

const [, ix] = await registerDomainName(name, space, buyer, buyerTokenAccount);

// sign and send the instruction

API

Registration instructions can also be created via API (equivalent to using the SDK):

GET https://sns-sdk-proxy.bonfida.workers.dev/register?buyer={buyer}&domain={domain}&space={space}&serialize={serialize}

This endpoint can be used to register domain for buyer. Additionaly, the buyer dans specify the space it wants to allocate for the domain account. In the case where serialize is true the endpoint will return the transaction serialized in the wire format base64 encoded. Otherwise it will return the instruction in the following format: { programId: string, keys: {isWritable: boolean, isSigner: boolean, pubkey: string}[], data: string } where data is base64 encoded.

This endpoint also supports the optional mint parameter to change the mint of the token used for registration (currently supports USDC, USDT, FIDA and wSOL), if mint is omitted it defaults to USDC.
