How to add a new token on STON.fi

Anyone can add a token to STON.fi by creating a v2 liquidity pool. This guide explains when it’s appropriate, how to do it safely, and how interface policies affect visibility.

STON.fi is permissionless: new tokens become swappable by creating a liquidity pool. This guide walks you through the process, what to check beforehand, and when a token may be hidden in the interface (even if the pool exists on-chain).

Before you start:

✅ Ensure you hold enough of both assets to seed the pool.

✅ Review STON.fi interface policies (taxable tokens, IP/impersonation) so you know how visibility works after creation.

When adding a token is appropriate

• You’re the token issuer or an authorized contributor.

• You’re listing a community token that does not violate IP or impersonate other assets.

• The token does not use fee-on-transfer (“tax”) mechanics or you accept that it will be filtered from the UI.

Step-by-step: add a token by creating a pool

1. Open STON.fi → Pools → Add liquidity.

2. In “Provide liquidity,” select the token pair for the pool (e.g., NEW/TON or NEW/USDt). If your token doesn’t appear by name, paste its contract address.

Configure the pool:

• Set the initial price by choosing amounts for each side.

• Review settings and click Preview pool creation.

Confirm:

• Check the popup details (pool parameters, fee from your wallet).

• Click Confirm pool creation and approve in your wallet. Pool creation and initial liquidity happen in one transaction.

After creation

• Your pool is live on-chain; swaps can route through it at the protocol level.

• If the token is compliant with interface policies, it will appear in app.ston.fi search by name. Otherwise, it may be accessible only by contract address — or hidden/blocked (see below).

Important limits: taxable tokens (fee-on-transfer)

To keep swaps predictable and safe, the STON.fi interface disables “taxable” (fee-on-transfer) tokens. Our AMM/aggregation contracts cannot reliably account for variable transfer deductions across multi-hop routes. What this means for you:

• You can still create a pool for a tax token at the protocol level.

• However, the token will not be surfaced or routed in app.ston.fi.

• Other third-party interfaces may still access the pool directly via the blockchain. Use caution and do your own research.

Important limits: intellectual property and impersonation

Per our Terms of Use, STON.fi hides tokens that:

• impersonate known assets (e.g., fake “USDt”, “BTC”),

• misuse brands, names, logos, or characters without permission,

• claim affiliation with legitimate projects when they are not.

Meme tokens are welcome when they’re original. Direct copies of protected brands are not.

Visibility rules in the interface

• Hidden: Some tokens won’t show up by name, but can be used if you enter the contract address manually. Responsibility is on you; verify what you’re adding.

• Blacklisted: Fraudulent tokens are blocked entirely in the UI (even by address). These rules affect only the app interface. Pools still exist on-chain and can be accessed programmatically or via other UIs.

FAQ

❓ Can I add a token name/logo? Token metadata is read from the ecosystem’s token registries and community resources. Names/logos may take time to propagate; always share the contract address so users can verify. ❓ Why don’t I see my token by name? It may be new (metadata not propagated), hidden (policy), or filtered (tax token). Users can still paste the contract address if it isn’t blacklisted. ❓ Can I create multiple pools for the same token? Yes, but liquidity fragmentation can worsen swap conditions. It’s usually better to build depth in one or two key pairs (e.g., NEW/TON or NEW/USDt). ❓ Does STON.fi “list” tokens? No approvals are needed at the protocol level. The UI applies safety filters to protect users; the protocol itself remains open and decentralized.
