An EVM-compatible testnet for Lit Protocol’s decentralized key management, enabling programmable signing with PKPs, access-controlled encryption, and cross-chain automation via Lit Actions using tstLPX.
Chronicle Yellowstone – Lit Protocol Testnet is the public test network for Lit’s Chronicle chain, a purpose-built blockchain for decentralized key management and threshold-cryptography (MPC/TSS) operations that uses tstLPX for gas. It is used to build and validate Lit Actions and Programmable Key Pairs (PKPs) for cross-chain signing, account abstraction, delegated wallets, access-controlled data, and automated multi-chain workflows without exposing private keys. Key metrics (Sep 2025): avg gas cost ≈ 0 tstLPX via faucet; block speed and TPS vary by validator set with no official benchmarks; activity is best verified in the testnet explorer for apples-to-apples comparisons.
It is unique because it specializes in verifiable, chain-agnostic signing and cryptographic automation rather than general-purpose smart contracts, letting one deterministic JS runtime (Lit Actions) control PKP-governed keys that can sign across EVM, Solana, and Cosmos ecosystems with on-chain rate limits and access control. Fast-finality BFT consensus and programmable access policies (e.g., OAuth proofs and on-chain conditions) provide predictable, low-cost execution in tstLPX for secure cross-chain workflows. For metrics comparison: avg gas cost is predictably low on testnet; block speed and TPS are not officially benchmarked and are secondary to successful cryptographic actions—check the explorer for current block interval, TPS, and activity trends.
