All major Solana wallets support .sol name resolution. In Phantom, you can type a .sol name in the recipient field and it resolves automatically. This dramatically reduces the risk of sending funds to the wrong address due to copy-paste errors.
Your .sol domain becomes your portable identity across the Solana ecosystem. Applications can display your domain name instead of your wallet address, making interactions more human:
.sol name as your username on Solana-native social appsYou can point your .sol domain to an IPFS content hash, effectively creating a decentralized website. The site's content lives on IPFS (censorship-resistant file storage) and is accessible through your .sol name.
How to set this up:
.sol domain via sns.idNote: Decentralized website hosting via .sol domains requires specific browser extensions or gateways to resolve. It's not as seamless as traditional domains yet, but it's improving.
Projects and businesses on Solana register .sol domains for brand presence:
jupiter.sol, raydium.sol, phantom.sol — major projects own their namesLike traditional domain names, .sol domains can be bought and sold on NFT marketplaces. Short, common English words, numbers, and brand-adjacent names carry premium value.

Open the KOL TrackerInstead of sending SOL to 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU, you can send it to alice.sol. That's the core value proposition of the Solana Name Service (SNS) — human-readable names that replace cryptographic wallet addresses for transactions, identity, and more.
Domain name services aren't unique to Solana. Ethereum has ENS (.eth domains), and virtually every major chain has some equivalent. But Solana's naming ecosystem has some distinct characteristics: it's cheaper, faster, and has multiple competing providers offering different TLDs (top-level domains). This guide covers all of it.
The Solana Name Service is a protocol built by Bonfida that maps human-readable .sol domain names to on-chain data — primarily Solana wallet addresses, but also IPFS content hashes, social profiles, and arbitrary records.
How it works technically:
.sol domain is an NFT (SPL token) stored in your Solana wallet.sol name to its underlying wallet address using the SNS SDK or APIKey stats (2026):
.sol domains registeredGo to sns.id (the official SNS frontend by Bonfida) and type your desired domain name.
The search will show:
.sol domain pricing is based on the length of the name:
| Domain Length | Annual Cost (approximate) |
|---|---|
| 1 character | $750+ |
| 2 characters | $300+ |
| 3 characters | $80+ |
| 4 characters | $20+ |
| 5+ characters | $2-10 |
Prices are denominated in USDC but can be paid in SOL, USDC, or other SPL tokens. Shorter names cost more because they're scarcer and more valuable — just like traditional domain names.
Important: .sol domains can be registered for 1-10+ years. You pay upfront for the registration period. There are no automatic renewals — if your domain expires and you don't renew, someone else can register it.
After registering, set it as your primary domain (also called "favorite domain"):
Your primary domain is what applications display next to your wallet address. When someone looks up your wallet, they'll see your .sol name instead of the raw address.
By default, your .sol domain resolves to the wallet that registered it. To change this (point it to a different wallet):
You can also add records for other blockchains — map your .sol domain to your Ethereum address, Bitcoin address, and others. This creates a universal identity across chains.
SNS supports various record types you can attach to your domain:
These records can be read by any application that integrates with SNS, creating a portable on-chain profile.
You can create subdomains under your .sol domain. For example, if you own alice.sol, you can create:
payments.alice.sol — A separate address for receiving paymentsnfts.alice.sol — A dedicated NFT collection addressdao.alice.sol — An address for DAO-related activitiesSubdomains are free to create (just a transaction fee) and can each point to different wallet addresses.
AllDomains is a platform that offers alternative top-level domains on Solana beyond .sol. These include community-driven TLDs tied to specific Solana projects and communities.
Available TLDs include:
| Feature | SNS (.sol) | AllDomains |
|---|---|---|
| Primary TLD | .sol | .bonk, .abc, .poor, etc. |
| Operator | Bonfida | AllDomains protocol |
| Wallet support | Universal | Growing |
| Marketplace | Multiple | AllDomains marketplace |
| Price range | $2-750+/year | Varies by TLD, often cheaper |
| Best for | Primary identity | Community identity, collecting |
Should you get an AllDomains name? If you're part of a specific Solana community (BONK holders, Superteam members, etc.), having a matching domain is a fun identity signal. But for practical use (sending/receiving funds), .sol domains have far wider support across wallets and applications. AllDomains names are increasingly supported but not yet universal.
Bonfida is the team that built the Solana Name Service protocol. Besides SNS, Bonfida also operates:
.sol domains.sol domain resolution into applicationsBonfida is essentially the Solana equivalent of what ENS Labs is to Ethereum Name Service. They built and maintain the core protocol, though the protocol itself is permissionless and open-source.
Some notable sales have been in the thousands of dollars for premium single-word domains.
Phantom has native SNS support:
.sol name instead of your wallet address. Anyone sending you SOL or tokens can type your .sol name in the recipient field.sol name in the "To" field when sending — Phantom resolves it to the underlying wallet address.sol domain appears next to your wallet address in the appMost Solana wallets now support .sol resolution:
When you connect your wallet to a dApp that supports SNS, your .sol name appears instead of (or alongside) your wallet address. This includes most major Solana DeFi protocols, NFT platforms, and social apps.
.sol domains expire. Set a reminder to renew before expiration:
Since .sol domains are NFTs, transferring them is like transferring any SPL token:
Caution: Once transferred, you lose all control over the domain. The new owner can change the wallet address it points to, update records, or sell it.
.sol name, verify the resolved address before sending large amounts. A .sol name could theoretically be compromised if the owner's wallet is hacked and records changedIf you're building on Solana and want to support .sol domain resolution:
JavaScript/TypeScript SDK:
import { resolve } from "@bonfida/spl-name-service";
// Resolve a .sol domain to a wallet address
const owner = await resolve(connection, "alice");
console.log(owner.toBase58());
// → "7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU"
Reverse lookup (address → domain):
import { reverseLookup } from "@bonfida/spl-name-service";
const domainName = await reverseLookup(connection, publicKey);
console.log(domainName);
// → "alice"
The SNS SDK is open-source and well-documented. Integration is straightforward — most apps can add .sol domain support in under an hour.
API alternative: Bonfida provides a REST API for domain resolution if you don't want to make direct RPC calls. This is useful for backends or services that don't maintain a persistent Solana connection.
| Feature | SNS (.sol) | ENS (.eth) |
|---|---|---|
| Chain | Solana | Ethereum |
| Registration cost | $2-750+/year | $5-640+/year |
| Transaction cost | under $0.01 | $5-50+ (gas) |
| Transaction speed | ~400ms | ~12 seconds |
| Total registrations | 3M+ | 2M+ |
| Subdomains | Free (tx fee only) | Free (gas only) |
| Multi-chain records | Yes | Yes |
| NFT standard | SPL | ERC-721 |
| Governance token | No | ENS token |
The practical experience is similar — both map human names to wallet addresses. SNS is cheaper and faster to interact with (because Solana), but ENS has deeper integrations across the broader crypto ecosystem and wider recognition outside of Solana.
Yes if:
Maybe not if:
.sol name linked to your wallet makes all your transactions easily trackable by anyone who knows your name)For most active Solana users, a .sol domain is a small, worthwhile purchase. The cost of a basic name is less than a single transaction on Ethereum, and the convenience of human-readable addresses is genuine. Start with a 5+ character name for under $10/year, and if you find yourself using it regularly, consider securing shorter or premium names.
