Metric Questions Answered
New to Metric or just curious about a detail? Below you'll find straight answers to the questions people ask most — from connecting a wallet to understanding fees. If something is still unclear, the project overview goes deeper into how the protocol is built.
What is Metric?
Metric is a decentralized exchange interface that lets you swap ERC-20 tokens directly from your wallet. There's no account, no sign-up, and no custody of your funds — trades settle on-chain through smart contracts. Think of it as a clean window onto liquidity pools rather than a company holding your crypto.
How do I make my first swap on Metric?
Connect a wallet, pick the token you're selling in the top pane, then choose what you want to buy. Enter an amount and the Metric platform quotes a rate automatically. Review the details, hit the swap button, and confirm in your wallet. The whole thing usually takes under a minute once your wallet is set up.
Which wallets work with Metric?
Most popular Ethereum-compatible wallets are supported, including MetaMask, Rabby, Coinbase Wallet, and WalletConnect-compatible mobile wallets. If your wallet can sign Ethereum transactions, chances are it works here. Hardware wallets like Ledger work too when connected through MetaMask.
What fees does Metric charge?
Metric takes no front-end fees — the note under the swap button isn't just marketing. You still pay the underlying pool's swap fee, which is set by the liquidity protocol (commonly 0.05%, 0.3%, or 1% depending on the pool), plus the network gas fee that goes to Ethereum validators. Nothing extra is skimmed on top by the interface.
Is Metric safe to use?
Swaps on Metric route through audited smart contracts — the same class of contracts battle-tested across DeFi since Uniswap launched in 2018. Your tokens never sit in an account controlled by the interface. That said, no one can remove all risk: always check token addresses yourself, because anyone can create an ERC-20 token with a familiar name.
Has the code been audited?
The underlying protocol contracts follow patterns similar to those reviewed by firms like OpenZeppelin, and the routing logic relies on well-established pool contracts. Audit reports for the specific contracts Metric routes through are linked from the project page. Audits reduce risk — they don't eliminate it, so size your trades accordingly.
Why did my swap fail?
Usually it's slippage. If the price moves more than your tolerance before the transaction confirms, the contract reverts instead of giving you a worse deal. Low liquidity, a gas fee set too low, or a token with transfer restrictions can also cause failures. Try bumping slippage slightly in the settings gear, or split a large trade into smaller chunks.
What is slippage, and what should I set it to?
Slippage is the gap between the quoted price and the price you actually get when the transaction lands on-chain. For liquid pairs like ETH/USDC, 0.1–0.5% is typically fine. Volatile or thin tokens may need more. Set it too high and you open yourself to sandwich attacks — keep it as low as your trade allows.
Can I trade any token on Metric?
Any ERC-20 token with liquidity in a supported pool can be traded, even if it doesn't appear in the default list — paste the contract address into the token picker. Be careful, though. Verify addresses against the token's official site or a block explorer like Etherscan before swapping into an unfamiliar asset.
Do I need to create an account or pass KYC?
No. There's nothing to sign up for and no identity check — your wallet is your identity. Connect, swap, disconnect. That's the whole loop. It's worth remembering your wallet provider may have its own terms, but Metric itself collects no account data.
Why does Metric need token approvals?
Before a contract can move an ERC-20 token on your behalf, you have to grant it an allowance — that's how the token standard works. It's a one-time transaction per token per spender contract. ETH itself never needs approval because it's the network's native asset, not a contract-based token.
Can I provide liquidity through Metric?
Yes — head to the Pools section from the navigation. Adding liquidity means depositing a pair of tokens into a pool and earning a share of the swap fees that pool collects. Returns vary a lot by pair and volume, and impermanent loss is real, so read up before committing meaningful capital. The home page links straight into it.
Which networks does Metric support?
Ethereum mainnet is the primary venue, with the interface designed to extend to major L2 networks where the underlying pools operate. The token selector and network badge in the header always show which chain you're currently on — double-check it before confirming any transaction, since sending a trade on the wrong network is a common beginner mistake.
What analytics data does Metric collect?
Only if you opt in via the consent panel, Metric gathers anonymized usage data — which screens get used, where people drop off, that kind of thing. It helps the team decide what to fix next. Reject it and nothing is tracked. Either way, your wallet address and transaction history stay on-chain and out of the analytics pipeline.
Who do I contact if something goes wrong?
Start with the project page for documentation and community links. For failed transactions, the hash on the block explorer usually tells you exactly what happened. Since Metric is a non-custodial interface, there's no support desk that can reverse a swap — the blockchain is final, so treat each confirmation screen seriously.
