Sign Introduces Foundry Deployer to Bring Production-Grade Deployment to Ethereum

Over the past decade, Ethereum development has matured significantly. Frameworks like Foundry and Hardhat have transformed local testing, while libraries from OpenZeppelin have standardized secure smart contract design, and indexing layers such as The Graph have made onchain data usable.

Together, these tools have streamlined development within the vast Ethereum ecosystem and changed how smart contracts can be designed, tested, deployed, and utilized.

However, as the ecosystem scales toward an increasingly multi-chain future, a new challenge has emerged: the growing complexity of production-grade deployment and consistent version management across diverse networks.In order to close this gap, Sign, the digital sovereignty infrastructure provider, has released the Foundry Deployer.

The Foundry-based deployment and versioning framework is extracted from TokenTable that the Sign team has used extensively in production.

“Back when I first started learning Solidity in 2018, most of the developer luxuries we take for granted today simply didn’t exist,” said Jack Xu, CTO of Sign, sharing the inspiration behind the latest product.

“There were far fewer tools, limited testing frameworks, no local EVM stack traces, and no console logs. Debugging often meant guessing, commenting out lines of code one by one, and hoping I had isolated the issue. Contract deployment was convoluted, and there was no efficient way to index or reason about emitted events. It was a highly manual and demanding process but it was also here we developed the rigorous standards we apply to our infrastructure today,” added Xu.

But the maturation of the Web3 open-source ecosystem and the available tooling helped the team build EthSign, TokenTable, and Sign Protocol. As these products evolved, so did their own internal tooling, resulting in automated and field-tested infrastructure.

“These tools helped us move faster, reduce risk, and maintain consistency as our systems grew in complexity,” Xu said. “Today, we’re finally in a position to give back to the developer community that carried us through those early waves.”

Accordingly, the team has now introduced “Built by Sign,” an effort to open-source core tooling that they’ve built. Extracted from real systems, it is built for teams operating at scale.

The first repository made public is Foundry Deployer, a Foundry-native framework built around deterministic CREATE3 deployments with version management, JSON tracking, and GitHub Actions integration.

The goal, with this initiative, Yan noted, is to make it easier for other developers and teams to build, deploy, and maintain on-chain systems with greater confidence and efficiency.

This practical, production-tested infrastructure is just the beginning, with the Sign team committed to empowering the community by open-sourcing the battle-tested infrastructure that powers our ecosystem, with upcoming releases for Solana, Aptos, Hyperledger Fabric, and beyond.
