TON Wallet Became DeFi Account; Cross-Chain Deposits Now Use swaps.xyz

TON Wallet’s cross-chain funding feature remains available, but the product is now called DeFi Account and swaps.xyz processes transfers that originate outside TON. The interface still turns supported assets from other blockchains into TON-network balances rather than holding those assets on their original chains.

The original funding shortcut therefore survives, while some launch-era details no longer describe the live service. Cross-chain USDT withdrawals are now available, charges can affect the amount received, and every address generated for a non-TON deposit is valid for one transfer only.

The launch model and what changed

MoonPay introduced the original integration on February 11, 2026. The company’s MoonPay Deposits launch notice described a self-custodial TON Wallet flow in which its infrastructure detected incoming funds, completed the necessary swap and routing operations, and delivered the selected TON-supported asset.

That design addressed a narrow but significant problem. A holder of cryptocurrency on another network could fund TON Wallet without separately choosing a bridge, moving funds through an exchange and completing several connected transactions. The user still had to select the source asset and network correctly, but the conversion route was handled within a single deposit flow.

The present interface follows the same broad model with a different processor. For non-TON deposits, swaps.xyz now performs the third-party conversion under its own limits and terms. This is a provider change, not a conversion of DeFi Account into a wallet that natively stores balances across several blockchains.

TON Wallet is now DeFi Account

The official DeFi Account description records that TON Wallet was renamed on May 27, 2026, while its blockchain addresses, assets and access arrangements remained unchanged. It defines DeFi Account as a non-custodial TON address developed by TON Space Ltd. and also states that Wallet is an independent service not affiliated with Telegram, despite being accessible through the messaging application.

This account should not be confused with Crypto Wallet, the separate custodial component within Wallet. DeFi Account gives the user control of the private key and recovery phrase; Wallet supplies the interface but does not hold those credentials or control the funds at the address.

A second naming change affects the asset received from some cross-chain deposits. Toncoin was renamed Gram (GRAM) on June 15, 2026, while the blockchain retained the TON name. The rename did not require a migration, token exchange or new address, so references to GRAM and the former TON ticker can describe the same native asset at different points in the product’s history.

Supported routes, fees and receiving assets

The current DeFi Account transaction instructions identify swaps.xyz as the processor for non-TON deposits and withdrawals, specify the supported routes below, and warn that each generated cross-chain deposit address can be used only once. They also state that stablecoin deposits use the exchange rate displayed in the interface and may include a third-party provider fee, while BTC, ETH and SOL deposits carry a 0.9% conversion fee into GRAM.

• USDT can arrive through TRON, Ethereum, BNB Smart Chain, Solana, Arbitrum or Polygon and is converted into USDT on TON.
• USDC can arrive through Ethereum, Solana, Base, Arbitrum or Polygon and is also converted into USDT on TON.
• BTC sent through Bitcoin, ETH sent through Ethereum and SOL sent through Solana are converted into GRAM on TON.
• Cross-chain withdrawals are available for USDT, including an option to convert the outgoing amount to USDC on a supported destination network.

The list reveals the central limitation: support is defined by an exact token-and-network combination. The presence of USDC on Base does not imply that USDT on Base is accepted, while support for SOL does not mean that arbitrary Solana tokens can use the same route. A transfer outside the documented combinations may not be recoverable through the intended deposit flow.

The amount credited should not be inferred solely from the source token’s face value. The operational figure is the receiving estimate displayed before the transfer, because the quoted exchange rate and provider charge can change the result even when both the sent and received assets are dollar-denominated stablecoins. The earlier description of stablecoin conversions as universally one-for-one is therefore too broad for the current service.

The generated address is a transaction instruction, not a saved destination

The most consequential difference from an ordinary wallet deposit is the single-use address. It represents a particular conversion order, including the selected source asset, network and destination asset, rather than a permanent TON address that can safely remain in an exchange address book.

A new cross-chain transfer requires a newly generated address. Reusing an address from a completed or abandoned order can separate the payment from the route for which it was created and may result in lost funds. The receiving estimate and provider conditions should likewise be reviewed for each new order rather than assumed from a previous transfer.

Network selection remains important even though the bridge and swap operations are hidden. The service reduces the number of visible transactions; it cannot correct a withdrawal initiated on the wrong blockchain or make an unsupported token compatible after it has been sent.

Cross-chain withdrawals make the service broader, but not symmetrical

The live service now supports outward cross-chain transfers for USDT, an option that was still presented as future functionality when deposits launched. This creates a bidirectional stablecoin route between TON and selected external networks, subject to the provider’s available destinations, minimums, quoted conversion and fees.

The same symmetry does not extend to every incoming asset. BTC, ETH and SOL deposits become GRAM, but the documented cross-chain withdrawal function does not offer a direct reversal from GRAM into the original cryptocurrency. Depositing BTC through the conversion service should therefore not be understood as creating a Bitcoin balance that can later be withdrawn unchanged.

DeFi Account’s cross-chain feature remains useful because it combines conversion and routing inside the wallet interface. Its trade-off is equally concrete: users accept a third-party route, a quoted rate, defined token-network pairs and a transaction-specific address instead of controlling each bridge or exchange operation separately.
