Silver Swap

SilverSwap is a non-custodial automated market maker on Sonic: you trade against liquidity pools through smart contracts, your wallet authorizes every transaction, and nothing is deposited with an intermediary. An automated market maker prices trades from pool liquidity rather than a central order book. SilverSwap's core is concentrated liquidity, so providers allocate capital inside chosen price ranges instead of spreading it across all prices the way constant-product pools do, and each position is minted as a transferable NFT. AG is the protocol token, with its Sonic contract publicly listed as 0x005851f943ee2957B1748957F26319e4f9EdeBC1. "Silver Swap" also appears in precious-metals contexts; the crypto protocol is the SilverSwap DEX on Sonic. A non-custodial design means the wallet holder controls the keys and authorizes the movement of funds, rather than depositing them with an intermediary; see this non-custodial wallet definition.

A SilverSwap swap routes through pool contracts: you pick two tokens and an amount, the interface pulls an on-chain quote, and the router executes against the relevant pool once you sign. Expected output is the quoted amount of the output token; price impact is what your own trade does to the pool price and climbs fast in thin pools; minimum received is the lowest output the transaction will accept, so the transaction reverts if the pool cannot deliver at least that amount. The first time you spend a token, you sign an ERC-20 approval before the swap itself; an ERC-20 token standard defines the transfer and approval interface that wallets and contracts use for fungible tokens.

SilverSwap's primary network is Sonic mainnet, an EVM-compatible layer-1 with chain ID 146 and S as the native gas token. Sonic's mainnet network settings list the same chain ID and currency symbol. Supported assets and routes depend on which pools are actually deployed and funded on Sonic right now: there is no permanent token list, and a token existing on-chain doesn't mean a usable pool exists. Before planning a trade, check live pool liquidity on a tracker, then confirm the route in the app itself.

Every swap has three cost components: the pool's fee tier, paid to liquidity providers and set per pool; Sonic network gas, paid in S and generally small but never zero; and price impact, a function of your trade size versus pool depth. The quote screen in the live app shows the effective numbers for your exact trade, so that quote—not a fixed figure—is the source of truth. Price impact is the pool-price change caused by your order; slippage in finance is the difference between the expected execution price and the price actually executed. For larger orders, compare quoted output across trade sizes because price impact is usually the cost that actually bites.

SilverSwap is auditable and inspectable, but it is not risk-free. Hashlock has published multiple audit reports on SilverSwap contracts, and the deployed code is publicly verifiable through the SonicScan code explorer, which gives you reviewability. What audits don't remove: smart-contract bugs outside audited scope, malicious or illiquid tokens, oracle and routing risk, approval misuse, and phishing interfaces impersonating the app. The realistic risk model is that most losses on DEXes come from user-side mistakes — wrong network, bad approvals, fake tokens — so your own verification habits matter more than any audit badge. None of this is financial advice.

To swap on SilverSwap, complete the standard EVM transaction flow in this order:

1. Open the official app and connect an EVM wallet set to Sonic (chain ID 146), with some S for gas.
2. Select the input and output tokens by contract address, not just ticker.
3. Enter an amount and read the quote: expected output, price impact, and minimum received.
4. If prompted, sign the ERC-20 approval; the spender is the SilverSwap router.
5. Sign the swap and wait for Sonic finality; output lands directly in your connected wallet.

An EVM transaction changes on-chain state only after the signed transaction is included. For liquidity rather than swaps, the documented flow is adding liquidity to an existing pool: you deposit two assets into a chosen range and receive an NFT for the position.

On Sonic, the fastest fixes are network, gas, approval, liquidity, and quote checks. Wrong network: if the app shows no pools or your balance looks empty, check that the wallet is on chain ID 146. No gas: S is required even when swapping other tokens; a zero-S balance blocks every transaction. Approval loop: if the swap stays greyed out, the approval has either not confirmed or is below the trade amount; re-approve with the correct spender. High price impact: shrink the order or find a deeper route instead of raising slippage to force a poor fill. Reverted transaction: slippage or minimum-received may have been triggered by a price move between quote and confirmation; requote and retry.
