Developer Activity

A decentralized, cross-chain protocol for stablecoin bridging and exchange.

Noether is a decentralized perpetual futures exchange built natively on Stellar/Soroban. It enables leveraged trading up to 10x (just for now) on crypto assets with limit orders, stop-loss, and take-profit functionality. Liquidity providers earn yield through the NOE-token vault system. Currently live on testnet with a complete trading interface, automated keeper infrastructure, and four production-ready smart contracts.

Trustless Work is a blockchain-powered Escrow-as-a-Service platform leveraging Stellar's Soroban smart contracts to provide secure, transparent, and efficient escrow solutions with minimal fees.

ACTA is a decentralized identity and verifiable credentials platform built on Stellar. It enables organizations and individuals to issue, share, and verify W3C-compliant credentials on-chain via Soroban smart contracts — no programming knowledge required. ACTA also implements the did:stellar DID method standard for portable, resolvable identity across the Stellar ecosystem.

The Stellar CLI is the official command-line tool for Stellar/Soroban developers. `stellar keys generate <name> --fund` generates a keypair and funds it with test XLM via Friendbot (the testnet faucet, ~10,000 XLM) — the fastest way to fund a testnet account. It also deploys and invokes contracts, starts local testnets, and manages keys, accounts, and XDR.

Smart Account Onboarding is an open-source reference implementation and onboarding standard that removes the primary adoption friction for Soroban smart accounts: funding a C-address without forcing end-users to first create and manage a traditional G-address. The project delivers: a G→C seamless funding bridge (supporting inbound funding from existing G-addresses, CEX withdrawals, and optional off-ramp rails), making the “G-address step” transparent or unnecessary for the user, a production-grade reference C-address wallet (web + mobile) with token holdings and transfer history at parity with Freighter, a reusable Onboarding Kit (UI + SDK) that wallet providers can embed to standardize the “create C-address → fund fees → add assets → bridge funds” journey across the ecosystem. Implementation aligns with the OpenZeppelin Smart Account standard, using its smart-account primitives (policies/signers/verifiers) to support modern auth patterns and extensibility.

Nethermind is a leading blockchain research and software engineering company building core infrastructure for decentralized systems. On Stellar, Nethermind delivers ZK infrastructure including Stellar Private Payments (SPP) — a privacy-preserving payment protocol — a Stellar ↔ Wormhole cross-chain bridge, and a RISC Zero ZK verifier.

Decentralized commodity trade finance platform that generates on-chain yield from asset-backed commodity financing trades. Pipeline targets the ~$2.5 trillion trade finance gap — widened by Basel III regulatory changes that made short-duration commodity-backed lending to mid-market traders uneconomic for banks — by providing institutional-grade rails for digital asset investors to access high, asset-backed yield with short duration (30–180 days). Built on Soroban/Stellar with institutional custody (BitGo), KYC/AML screening, and a 3-of-5 Risk Council multisig governance structure.

Templar is a decentralized 'cypher lending' protocol that lets Stellar users borrow USDC against XLM collateral directly from their Stellar wallets, without bridges or wrapped tokens. It uses NEAR's multi-party-computation (MPC) network and Chain Signatures to custody deposits and settle cross-chain. On Stellar the collateral asset is XLM; Bitcoin-collateral and Ethereum/NEAR markets exist on its other deployments. The Stellar integration was announced November 2025.

PG Atlas is the objective, transparent metrics backbone for the SCF Public Goods Maintenance program. Its primary role is to shift public goods funding decisions from noisy, subjective signals to verifiable, data-driven insights by quantifying adoption, criticality, reliability, security/quality, and decentralization (risk) across open-source tools, libraries, explorers, RPC infrastructure, SDKs, and other foundational components in the Stellar/Soroban ecosystem. By providing a live dependency graph, transitive impact scoring, pony factor analysis, and an active subgraph projection, PG Atlas directly powers the Metric Gate in the proposed funding decision stack and supplies off-chain context for NQG-weighted voting in the community-led Public Goods decentralization pilot.
