Deploy Token
Generate, deploy and verify an ERC-20 on Base.
Deploy Token generates and deploys your own ERC-20 on Base. You get a tax, limits and an anti-snipe whitelist, and the contract is built to work with Custom Bundle from the start. It has three steps. You can move between them freely, and a draft is saved as soon as you save step 1.
Contract templates
| Template | How tax works | Owner tax control |
|---|---|---|
| Clog (default) | Starts at the initial buy/sell tax and drops to the final tax after N transactions. The Clog % is taken once, when the contract seeds its own pool | Reduce Fee jumps straight to the final tax |
| Standard Tax | Fixed buy and sell tax | Can only be lowered, never raised |
Step 1 — Token Details
| Field | Default | Notes |
|---|---|---|
| Token Name / Symbol | — | Required |
| Total Supply | 100,000,000 | Minted entirely to the deployer |
| Token Decimals | 9 | 0–18 |
| Contract Socials | — | Stored with the deploy. Not written into the contract |
| Clog (%) | 15 | Clog only. Max 50 |
| Initial Buy / Sell Tax (%) | 15 / 15 | “Buy / Sell Tax” on Standard Tax. Max 50 |
| Final Buy / Sell Tax (%) | 0 / 0 | Clog only |
| Reduce Tax After (Transactions) | 20 | Clog only |
| Max Transaction / Max Wallet (%) | 2 / 2 | Above 0, up to 100 |
| Swapback Threshold (%) | 0.1 | When collected tax reaches this share of supply, it is swapped to ETH and sent to the tax wallet |
| Max Swapback (%) | 1 | Largest single swapback |
| Anti-Snipe Window (blocks) | 15 blocks (~30 s) | Only whitelisted wallets can buy in this window. 0 turns it off |
| Custom Tax Wallet | Off | Send taxes to another address instead of the deployer |
Step 2 — Deployer Setup
If you have a ★ default dev wallet, click Use this wallet on its card. Nothing to paste. Otherwise paste a private key under Enter deployer private key. A pasted key stays in the page's memory only. If you reload, you have to enter it again.
Step 3 — Deploy
- Estimate GasShows Current Network Fee (gwei) and Estimated Gas Cost (ETH).
- DeploySends the creation transaction and waits for the receipt. If the RPC returns "nonce too low", it retries automatically up to 3 times.
Manage Token opens the owner panel. Open Terminal opens the token in the Terminal, to trade it once it has a pool. Bundle this token → opens Custom Bundle with the token, trading function, whitelist function and Max Tx already filled in. Pick a fee tier and click Fetch Token Data.
What the contract does
- The full supply is minted to the deployer, and the Uniswap V2 pair is created at deploy time.
- Before
openTrading()you must send both ETH and tokens to the contract. Otherwise it reverts with No ETH seeded or No tokens seeded.openTrading()adds all of it as liquidity, and the LP tokens go to the owner. - During the anti-snipe window only addresses whitelisted through
configureLaunch(address[], bool)can buy, and they pay no tax. Anyone else gets Trading unavailable. - Max transaction and max wallet limits apply to buys until you call Remove Limits.
- Automatic swapbacks are limited to 4 per block.
Next
Seed the contract, whitelist any extra addresses and open trading from Manage. Or let Custom Bundle open trading and buy with your wallets in one run.
Deploy Token charges no platform fee. You pay gas only.
