Frequently Asked Questions

Mexas is a stablecoin designed for the Mexican market. It is built to follow the value of the Mexican Peso, so one unit is intended to behave like one peso rather than like a volatile cryptocurrency.

It combines blockchain settlement — transactions that clear in seconds, around the clock, to anyone with a wallet — with reserves held in regulated financial institutions.

Anyone who needs to hold or move pesos digitally: shoppers paying at stores that accept it, people sending remittances into Mexico, businesses settling with partners, and traders who want a peso-denominated asset on-chain instead of converting to dollars.

Bitcoin and Ether float — their price is whatever the market decides moment to moment. Mexas is a stablecoin: its design goal is to hold a steady value against the Mexican Peso, backed by reserves rather than by speculation. You would use Bitcoin to speculate; you would use Mexas to pay for something.

Mexas is issued on five EVM networks and the Liquid Network. Each is a separate ledger with its own supply — a balance on one is not automatically a balance on another, and there is no bridge between them.

On the EVM networks Mexas is a standard ERC-20 token, symbol MEX, 6 decimals:

• Ethereum (chain ID 1) — 0x6E8B146AF16429b037ecE5943F3c0E5f412ddFA7
• Arbitrum One (42161) — 0xc4c2EdE4F6fD623ACc86C492BDF099b3bA2B8303
• Avalanche C-Chain (43114) — 0x6E8B146AF16429b037ecE5943F3c0E5f412ddFA7
• Base (8453) — 0xc4c2EdE4F6fD623ACc86C492BDF099b3bA2B8303
• BNB Smart Chain (56) — 0x405E5F9C7D6F6E9f03a5b64e275f374507734fD6

Note that the same address appears on more than one network. Those are separate contracts with separate supplies, so always use the address for the network you are actually on.

On the Liquid Network, a Bitcoin sidechain, Mexas is an issued asset with ticker MEX and precision 8. Liquid has no contract addresses — assets are identified by a 32-byte asset ID:

26ac924263ba547b706251635550a8649545ee5c074fe5db8d7140557baaf32e

Every one of them can be inspected on that network's block explorer; the list further down this page links to each one.

Anyone can deploy a token on any of these networks, or issue an asset on Liquid, and call it “Mexas”. Before you buy, receive or add the token to a wallet, verify the address character by character against the one published on this page.

• Treat the address on this website as the source of truth. Do not trust an address pasted into a chat, a social media reply or a search advertisement.
• Check the whole string, not just the first and last few characters — scam addresses are routinely generated to match at both ends.
• If an identifier you were given differs by even one character, it is a different token. Stop.
• Check you are looking at the right network. Each network has its own address, the Liquid asset ID is not a contract address, and an address that is Mexas on one network may be something else entirely on another.

If you are unsure, email contact@mexas.io before moving any funds.

On the EVM networks: any wallet that supports the network in question and custom ERC-20 tokens. Switch the wallet to that network, choose “import” or “add custom token”, and paste the address for that network from above; the name and decimals are read from the contract automatically.

You will also need a small amount of the network's own currency to pay fees — ETH on Ethereum, Arbitrum and Base, AVAX on Avalanche, BNB on BNB Smart Chain — in the same way you need change in your pocket to post a letter.

On Liquid: any Liquid-compatible wallet, plus a small amount of L-BTC for fees. Because the Mexas asset is not yet listed in the Liquid Asset Registry, some wallets will show the raw asset ID rather than the name “Mexas” — that is expected, and not a sign you have the wrong asset.

For a wallet built for Mexas specifically, see MexasWallet.

Mexas itself charges no transfer fee. You pay the fee of whichever network you are transacting on, in that network's own currency. On layer-2 networks such as Arbitrum and Base this is typically a fraction of a cent per transfer; on Ethereum it is considerably more. Fees rise and fall with network demand.

No. Blockchain transfers are final and cannot be recalled by us or by anyone else. Always send a small test amount first when paying a new address, and confirm that you and the recipient are on the same network — Mexas sent on one network does not arrive on another.

On the EVM networks, yes — and we would rather you heard it here than found it in the contract. The token contract lets the issuer block an address, which freezes its balance in place, and then destroy that balance outright. It also lets the issuer pause all transfers at once. These are the controls a regulated fiat-backed issuer needs in order to comply with a court order or a sanctions listing, and most peso- and dollar-backed stablecoins have equivalents.

Two things bound them. They can only be exercised by a multisig wallet, so no single key holder can act alone, and every use is a permanent public event on-chain that anyone can audit. To date none of them has ever been used — no address has been blocked, no balance destroyed, and the token has never been paused on any network.

The Liquid asset has no such mechanism: there is no way to freeze or destroy a Liquid balance. The whitepaper sets out exactly what the controls are and how to verify all of this yourself.

Yes. The token contract was audited by CertiK, with a final report published on 12 May 2026. It found no critical, major or medium issues. Two findings concern the owner role’s powers, mitigated by multisig ownership on every network, and one minor coding-style finding was acknowledged.

The contracts deployed on every network run the audited code. The full report is on the Audit Reports page, and also listed on CertiK Skynet. A security audit covers the code, not the reserves — see where the reserves are held.

Mexas is a reserve-backed stablecoin. Tokens are issued against peso-denominated reserves and redeemed against those same reserves, so the token holds its value because it is a claim on an underlying asset rather than because a market decides it should.

Issuance and redemption happen wholesale, with liquidity providers rather than with individual holders: a provider sends pesos to the issuer and receives Mexas, and the reverse to redeem. Because there is a party standing ready to buy and sell Mexas against pesos, the peg does not depend on open-market trading alone.

Each quarter an independent accounting firm, Ferrer & Asociados, checks the peso reserves against the Mexas in circulation and reconciles bank movements against on-chain movements. Every report is published on the Audit Reports page — see also the whitepaper.

Reserves are held in bank accounts with financial institutions. Every quarter the accounting firm Ferrer & Asociados checks those balances against the Mexas in circulation on every network, and its reports are published in full on the Audit Reports page. At the latest snapshot, 31 March 2026, reserves of MXN 12,489,352.98 stood against 8,132,290.13 MEX in circulation.

Bank balances are not public, so on the reserve side you are relying on the auditor’s review rather than checking the figures yourself. Each report is a snapshot at the end of a quarter, not a continuous view.

Separately, the token side of the ledger is public and permanent on every network: total supply and every transfer are visible on each network's block explorer, without needing to take anyone's word for it. The list on this page links to all of them.

A stablecoin can trade below its reference value if the market doubts the reserves or if liquidity dries up temporarily. Mexas is not a bank deposit and is not insured; holding it carries risk. Read the risk disclosures in the Terms & Conditions before acquiring the token.

Through an authorised distribution partner. Mexas is distributed through partners who onboard customers under their own terms and identity checks, rather than sold directly by the issuer.

Once you hold Mexas you can move it to MexasWallet, a non-custodial wallet, if you would rather hold the token yourself. Non-custodial means you hold the keys: nobody, including us, can spend from your wallet or recover it for you if you lose your seed phrase. That is the trade-off — full control, full responsibility. It is not the same as saying the token has no issuer controls; see Can Mexas be frozen or seized? below.

You can also hold Mexas in any wallet that supports the network you are using: any ERC-20 wallet on Arbitrum One, or any Liquid-compatible wallet for the Liquid asset.

To buy or redeem Mexas through a regulated distributor, yes — anti-money-laundering rules require identity verification. Receiving Mexas from someone else in a self-custodial wallet does not involve us.
