Frequently Asked Questions

ImplicitEx uses Polygon because it provides fast confirmation times and low network fees while supporting USDC and widely used wallets. Transfers on Polygon typically settle quickly and cost significantly less than the same transaction on Ethereum mainnet, making it practical for moving smaller amounts of value without the gas cost consuming a large portion of the transfer.

See What is Polygon? in Learn.

ImplicitEx focuses on USDC because users generally want to transfer value, not speculate on price changes during the transfer process. USDC is designed to maintain a stable value close to $1.00 per token, which makes it more predictable for transfers, payments, and remittances than assets that fluctuate significantly in price.

USDC is issued by Circle. ImplicitEx does not issue, hold, or redeem USDC.

See What is USDC? in Learn.

What if I do not already have a wallet or USDC?

ImplicitEx requires a self-custody wallet that can connect to Polygon and sign transactions. MetaMask is the primary desktop wallet supported by ImplicitEx. Install it only from official sources, create a wallet, and save the recovery phrase offline before adding funds.

If you are starting from scratch, see the dedicated Start guide, which covers the full setup process in one place.

To create and fund a wallet for ImplicitEx:

• Install MetaMask from the official MetaMask site or your browser's verified extension store.
• Create a new wallet and write the recovery phrase down offline. Do not store it in screenshots, email, cloud notes, or chat apps.
• Add Polygon mainnet in MetaMask if it is not already available.
• Buy USDC through a supported exchange or on-ramp, then withdraw it to your wallet address on the Polygon network.
• Keep a small amount of MATIC on Polygon in the same wallet so the wallet can pay network gas.

To use ImplicitEx, the wallet needs native USDC on Polygon for the transfer amount and a small amount of MATIC on Polygon for network gas. If you buy USDC through an exchange or on-ramp such as Coinbase, confirm that you are withdrawing or receiving the Polygon version of USDC before sending it to your wallet. Sending the wrong asset or using the wrong network can put funds at risk.

Useful starting points: MetaMask setup, buying crypto in MetaMask, and Coinbase USDC. These are external services; review their fees, availability, identity requirements, supported networks, and terms before using them.

See What is a wallet? and MetaMask in Learn.

I have never used a crypto wallet before — how do I start?

If this is your first time, follow these steps in order before using ImplicitEx. Each step builds on the previous one, so do not skip ahead.

• Install MetaMask.
  Download it from metamask.io or your browser's verified extension store. Do not install wallet software from third-party sites, search ads, or links in messages.
• Create a wallet.
  MetaMask will generate a new wallet address for you. If you already have a MetaMask wallet, you can import it using your recovery phrase instead of creating a new one.
• Write down your recovery phrase offline.
  MetaMask will show you a 12-word recovery phrase. Write it on paper and store it somewhere secure. Do not photograph it, type it into notes apps, email it to yourself, or save it in cloud storage. Anyone who has your recovery phrase controls your wallet.
• Add Polygon network.
  MetaMask may already include Polygon. If not, you can add it inside MetaMask under Networks, or visit the Polygon documentation for the network details. Make sure you are adding Polygon mainnet, not a testnet.
• Obtain USDC on Polygon.
  You need two things in your wallet: USDC on Polygon (the amount you want to send, plus the 1% platform fee), and a small amount of POL on Polygon to pay network gas. You can buy USDC through a supported exchange or on-ramp such as Coinbase. When withdrawing, confirm you are sending USDC on the Polygon network, not Ethereum or another chain.
• Connect your wallet.
  Return to ImplicitEx and click Connect Wallet. Select MetaMask and approve the connection. ImplicitEx will not request any transaction at this point — it only reads your wallet address and balance.
• Execute a transfer.
  Enter the recipient address and amount. Review the transfer summary carefully — verify the recipient address, amount, fee, and total debit before confirming anything in MetaMask.

If you run into difficulty at any step, the Learn page covers wallets, USDC, Polygon, and gas fees in more detail.

The first wallet confirmation authorizes the ImplicitEx contract to transfer the exact USDC amount. The second confirmation sends the funds. Authorization alone does not move any money.

This two-step process is a security feature of the ERC-20 token standard, not something specific to ImplicitEx. Your wallet controls the funds. The ImplicitEx contract cannot move USDC unless you explicitly authorize it first. The authorization is scoped to the exact amount of the transfer — it is not an unlimited approval.

See Token approval in Learn for how ERC-20 authorizations work.

They are paid to different parties for different reasons.

• Platform Fee — 1% of the transfer amount, paid to ImplicitEx. Shown in the transfer preview as part of the total debit.
• Network Gas Fee — paid to the Polygon network validators that process the transaction. Varies based on network conditions. ImplicitEx does not receive it.

The platform fee is fixed and displayed before you confirm anything. Gas fees are estimated by your wallet and are not collected by ImplicitEx.

See Gas and network fees in Learn.

Wallet security providers like Blockaid analyze contracts and assign a trust level based on factors that include transaction history, contract age, and known malicious patterns. A warning that a contract is "untrusted" means it has not yet accumulated enough history to receive a trusted classification — not that malicious behavior has been detected.

The contract address shown in the warning is the ImplicitEx contract. Its source code is publicly verified on Polygonscan. A controlled mainnet transaction was executed on June 15, 2026 prior to public launch, confirming that the contract routes funds exactly as described: the transfer amount to the recipient, the 1% fee to the treasury, and nothing retained by the contract. You can verify this directly on the Verification page.

If you see this warning, you can verify the contract address shown matches the address on the Verify page before proceeding. If they match, you are interacting with the correct contract.

See Why does my wallet show a warning? in Learn.

Some wallets use automated security screening to warn users before they approve token permissions or contract interactions. During ImplicitEx launch testing, MetaMask displayed a warning during the USDC approval step, before the transfer execution step.

The approval amount shown by ImplicitEx was exact: the transfer amount plus the displayed platform fee. ImplicitEx does not request unlimited USDC approval. The authorization is always scoped to the specific amount of that transfer.

The approval step and the transfer execution step are separate. Approving does not move funds. Funds only move when you confirm the second wallet prompt. If you see a warning on the approval step, you can verify the spend amount shown matches the total debit displayed by ImplicitEx before proceeding.

ImplicitEx has submitted a false-positive report with Blockaid, the security provider that powers MetaMask warnings. The warning reflects the contract's limited transaction history during early launch, not a finding of malicious behavior. The platform remains operational while the review is in progress.

See Verify — Wallet Security Warnings for the full context, including how to verify the contract address shown in the warning against the contract address published by ImplicitEx.

The transaction will still execute. Once a transfer is confirmed on-chain, it cannot be reversed by ImplicitEx, the recipient, or the blockchain network. If the destination address is wrong, the funds may be permanently inaccessible. ImplicitEx has no mechanism to recover, reverse, or retrieve a completed transfer.

This is why ImplicitEx shows the recipient address, amount, platform fee, and total debit before any wallet action, and asks you to confirm that you have reviewed them before proceeding.

Always verify the recipient address carefully. Transfers confirmed on-chain cannot be reversed.
