On October 28, VIA Labs launched a bidirectional messaging link between Stellar and Ethereum, enabling developers to connect smart contracts and transfer supported tokens. The company revealed the deployment at Stellar’s Meridian conference in Lisbon, Portugal.
This service connects Soroban contracts with Ethereum Virtual Machine applications across both mainnets and testnets, with VIA releasing specific gateway and token contract addresses.
The platform is designed for stablecoin transactions, tokenized real-world assets, and applications requiring synchronized contract execution. To demonstrate how transfers function, VIA introduced a reference token named VIAT, though developers retain the ability to design custom token contracts and message workflows.
Stellar-Ethereum Link Opens Two-Way Contract Messaging
Enabling developers to trigger Ethereum actions from Stellar contracts—or vice versa—is handled by VIA’s gateways, which ingest messages from application contracts and route them to destination contracts. This architecture allows an application to initiate a process on one network and finalize a corresponding step on another.
While the primary deployment connects both mainnets, VIA also offers a distinct pathway linking the Stellar testnet to Ethereum Sepolia. Teams can utilize the published network identifiers and contract addresses to locate appropriate gateways for specific environments.
Protocol messages cannot be sent directly from standard wallet accounts; instead, application smart contracts must invoke the gateway, leaving users to interact directly with the token or service contract rather than the messaging infrastructure.
Beyond the VIAT transfer demonstration, developers can integrate custom contracts for stablecoin management, tokenized assets, and automated cross-network operations.
VIAT Transfers Rely on Validator Signatures
The VIAT demonstration executes value transfers via a burn-and-mint mechanism. A transfer initiates when a contract destroys a designated token amount on the source chain, subsequently dispatching a message detailing the recipient address, amount, and an optional memo.
VIA validators monitor the source gateway and sign the message. A relayer then transports these signatures to the destination gateway, which validates them prior to directing the target token contract to mint an equivalent amount. According to VIA, this process maintains consistent token supply and prevents duplicate transmissions. VIA manages the validators, gateways, and relayers responsible for authenticating and routing messages between the two blockchains.
Transfer completion times are estimated between one and three minutes, varying according to validator polling frequency and relayer submission speeds.
Because Stellar utilizes seven decimal places and Ethereum uses 18, VIA’s client handles value conversion, ensuring that a transfer of five VIAT arrives as precisely five VIAT on the destination network.
Users remain responsible for standard network transaction fees, paid in XLM on Stellar or gas on Ethereum. For the launch period, VIA has waived its protocol fee for Stellar routes, and its relayers cover destination transaction costs.
Furthermore, Stellar recipients must have funded accounts; VIA cautions that transferring tokens to a previously uninitialized Stellar account can result in permanently unrecoverable funds.

Meridian Announcements Expand Stellar Tokenization Plans
Stellar highlighted the deployment during the October 28–29 Meridian conference, where VIA representative Jake Salthouse engaged with developers in Lisbon. Additionally, VIA reported that Hashlock has audited its VG1 contracts.
This new infrastructure arrives on the heels of Stellar’s September integration of USDT0 liquidity via LayerZero, a framework supporting USDT-related token transfers alongside partners such as Kraken, Bitget, and Fireblocks. VIA’s system distinctively supports developer-defined contract messaging in addition to transfers.
Concurrently, Securitize announced on October 28 its intention to integrate Stellar as the 17th blockchain supporting its regulated asset issuance and management services. Securitize counts BlackRock, Apollo, and Hamilton Lane among its clients, though this integration is not yet finalized.
In related news, the Depository Trust and Clearing Corporation (DTCC) outlined anticipated Stellar integration for tokenized securities. While its current tokenization service includes 20 institutional participants, the organization projects a public-network launch by 2027. For developers actively testing VIA, a faucet provides 100 VIAT per request on the Stellar testnet and Ethereum Sepolia, though teams must update testnet addresses to accommodate Stellar’s quarterly testnet resets.
Conclusion
VIA Labs’ Stellar-Ethereum integration provides bidirectional contract messaging alongside VIAT token transfers. While gateways, validators, and relayers manage message verification for developer applications, operational requirements include funded Stellar accounts and standard network transaction fees for mainnet and testnet users.
