iziSwap

iziSwap is a non-custodial decentralized exchange and automated market maker (AMM), not a blockchain, wallet, bridge, or centralized exchange. You connect your own EVM wallet and trade against liquidity pools through smart contracts; no account is created and no one holds your keys.

Its Discretized-Liquidity AMM allocates liquidity at discrete price ticks instead of across the whole curve like a constant-product AMM, the pool-based model described in AMM research. That concentrates liquidity where trades can use it, improving capital efficiency and reducing slippage at those ticks. The same design supports native limit orders: an order executes against on-chain pool liquidity rather than an exchange-held order book, so iziSwap never takes custody of the user's funds.

A swap settles atomically in one transaction: periphery contracts call the core pools, consume liquidity across price ticks, and transfer both tokens in the same execution. The quoter simulates that route and returns expected output, pool fee, price impact, and minimum received.

Price impact is the change your order causes while it consumes thin ticks; minimum received is the output floor encoded for the swap. If the route cannot meet its slippage tolerance, the transaction reverts instead of settling below that floor, a behavior covered by DEX interface guidance. A first trade of an ERC-20 token uses a separate approval transaction before the swap transaction.

iziSwap is deployed across multiple EVM chains, with major deployments on BNB Chain (chain ID 56), Polygon (137), zkSync Era (324), Arbitrum One (42161), Mantle (5000), Base (8453), and Linea (59144). Further deployments and protocol-based DEX-as-a-Service instances are listed in the developer overview and contract registry.

Your selected network determines which pool and token contract the transaction reaches: the same pair on two chains is two different pools with different liquidity. A token is tradable only where a pool exists on the selected chain with sufficient liquidity, so token availability is chain-specific rather than a permanent universal list.

A swap on iziSwap costs a pool fee, network gas, and the price impact created by the order. The pool fee comes from the selected fee tier: iziSwap pools exist at 1%, 0.2%, 0.04%, and 0.01%, and the applicable tier is shown with the pool. Volatile pairs typically use higher tiers, while stable pairs typically use lower ones.

Network gas is paid to the chain's validators and varies with congestion, not trade size; a required token approval adds another gas-paying transaction. Price impact is not collected by the protocol: it is the execution cost of moving through limited tick liquidity, while the resulting difference from the quoted execution is commonly called price slippage. The quoter's minimum-received figure is the useful total-output comparison because it reflects fee and impact together.

iziSwap is non-custodial and has published audits, but neither fact guarantees a safe outcome. Your wallet retains custody and signs transactions; audited open-source contracts reduce some risk without removing smart-contract, token, liquidity, or routing risk.

Before signing, use the genuine app, inspect the approval spender and amount, and verify token contracts independently rather than relying on a ticker. The remaining practical risks include unlimited approvals, phishing attacks, lookalike tokens, and limit orders or swaps against pools with almost no liquidity. Confirmed on-chain trades cannot be reversed.

To swap, connect a self-custody EVM wallet, select the correct chain, choose the pair, quote the route, approve the token if prompted, and sign the swap.

1. Connect the wallet and select the network your tokens are on; hold some of that chain's native token for gas.
2. Pick the token pair. For an obscure token, paste its verified contract address instead of searching by ticker.
3. Enter the amount and compare expected output, pool fee tier, price impact, and minimum received. High price impact identifies thin liquidity at the quoted ticks.
4. If prompted, sign the ERC-20 approval first; the ERC-20 standard defines the allowance that lets the contract spend the token.
5. Sign the swap. A market swap normally completes within one transaction's confirmation time. For a limit order, choose the target tick; it stays open until traded, canceled, or claimed, with no guaranteed fill time.

Wrong network. A zero balance or missing pair usually means the wallet is on a different chain; switch networks because swapping does not move assets between chains.

Cannot confirm — no gas. Every transaction, including an approval, needs the chain's native token (BNB, ETH, MATIC, etc.); fund the wallet before retrying.

Stuck on approval. Approval and swap are separate transactions. If approval confirmed but the swap did not appear, start the swap again; an old allowance can be revoked with an allowance tool, and the ERC-20 allowance interface is documented in OpenZeppelin's ERC20 reference.

Price impact is huge or the quote looks wrong. The pool has thin liquidity at the current ticks; reduce the trade size or check another chain or pool tier.

Transaction reverted. The route usually moved beyond its slippage tolerance or changed before confirmation. The revert costs gas but leaves the tokens in the wallet; request a fresh quote and use a tolerance that matches the intended execution.
