Network Upgrades and Forks
Documents Safe's singleton factory upgrades, canonical contract deployments, and version migrations across supported L1s and L2s. Operators, exchanges, and wallet teams use this group to track which Safe contract versions are canonical on each chain, when new deployments occur, and how proxy patterns and fallback handlers evolve. Distinct from governance in that it covers the technical activation and chain-specific rollout of new contract versions rather than the decision-making process.
Safe Singleton Factory Deployments
Chain-by-chain registry of official Safe singleton factory addresses and deployment transactions. Essential for wallet teams, exchanges, and custody providers to verify proxy authenticity on any L1 or L2. Chainscore can audit factory address verification logic and cross-chain deployment consistency.
Safe v1.3.0 Canonical Deployment and Activation
Definitive reference for the v1.3.0 contract release introducing EIP-1271 signature support. Tracks official deployment addresses and chain-by-chain activation timeline. Operators and integrators need this to confirm which chains run v1.3.0 as canonical and assess migration urgency.
Safe v1.4.1 Module and Guard Interface Overhaul
Technical breakdown of v1.4.1 singleton changes to module and guard interfaces, including the checkAfterExecution hook. Module developers and guard authors must understand these changes before upgrading. Chainscore offers upgrade readiness reviews for dependent module contracts.
Safe 2.0 Architecture and Multi-Chain Singleton Strategy
Explores the technical roadmap for a unified, chain-agnostic singleton architecture under Safe{Core} Protocol. Covers the shift from per-chain deployments to modular cross-chain account models. Protocol architects and wallet teams need this to plan long-term integration strategies.
Ethereum Mainnet Upgrade History and Canonical Addresses
Single source of truth for all Safe singleton and factory deployments on Ethereum L1, including block numbers, transaction hashes, and canonical version timeline. Exchanges and custodians rely on this for address verification and upgrade monitoring.
L2 Rollup Deployments: OP Stack Chain Activations
Tracks deployment quirks and activation status of Safe contracts across OP Stack chains including Optimism and Base. Addresses differences in factory addresses or singleton versions due to pre-deployed contracts or genesis state. Chainscore can verify deployment correctness for new OP Stack chains.
L2 Rollup Deployments: Arbitrum and Orbit Chain Activations
Documents Safe rollout across Arbitrum ecosystem, including Nitro-specific considerations and canonical deployment paths for custom Orbit chains. Orbit chain operators need this to ensure correct Safe deployment on their L3s.
L2 Rollup Deployments: zk-Rollup and zkEVM Chain Activations
Covers deployment patterns for Safe on zkSync, Starknet, Scroll, and Linea, including differences in account abstraction implementations and singleton adaptations for each zkEVM environment. Integrators need chain-specific guidance to avoid compatibility failures.
Alternative L1 and Non-EVM Deployment Registry
Registry for Safe deployments on non-EVM or EVM-incompatible chains through emulation or canonical wrapper patterns. Tracks technical compromises and version parity status. Teams building cross-chain Safe tooling need this to understand behavioral differences.
Safe Proxy Pattern Evolution: From v1.1.1 to v1.4.1
Technical deep-dive into how Safe proxy patterns have changed across versions, affecting initialization, storage layout, and upgradeability. Vital for security auditors and integrators assessing cross-version compatibility. Chainscore can review proxy upgrade paths for state integrity risks.
Fallback Handler Architecture and Versioning
Documents evolution of the fallback handler contract, how new handler versions are deployed, and how Safes migrate to gain features like token callback support. Wallet teams and relayers need this to ensure their Safes support current functionality.
Compatibility Fallback Handler for Legacy Safes
Focuses on the fallback handler designed to make older Safes compatible with modern tooling and transaction relayers. Explains the technical mechanism and activation process. Custodians with legacy Safe deployments need this to modernize without full migration.
SimulateTxAccessor and Contract Migration Helpers
Documents deployment and versioning of auxiliary contracts like SimulateTxAccessor critical for gas estimation and transaction simulation. Tracks how changes impact integrator tooling. Wallet and relayer teams need this to maintain accurate gas estimation.
Technical Guide: Migrating a Safe from v1.x to v1.4.1+
Procedural reference for operators and wallet teams detailing exact transaction sequences, delegatecall mechanics, and state migration steps to upgrade an existing Safe proxy. Chainscore can provide migration verification and state integrity checking services.
Cross-Chain Safe Deployment and Address Determinism
Explains technical guarantees and limitations of deploying a Safe at the same address across multiple chains using CREATE2. Covers nonce mismatch risks and chain-specific factory addresses. Multichain operators need this to avoid deployment failures.
Safe{Core} Protocol: ERC-4337 Compatibility Upgrades
Tracks technical rollout of Safe modules and singleton changes enabling native compatibility with ERC-4337 bundlers and EntryPoint contracts. Represents a significant architectural shift in Safe operation. Bundler integrators and wallet teams need upgrade guidance.
Post-Upgrade Verification and State Integrity Checks
Guide for operators on programmatically verifying Safe state integrity after singleton migration, including owners, threshold, modules, and fallback handler. Covers common failure modes and detection methods. Chainscore can automate post-migration verification for institutional operators.
Safe v1.x Contract Suite and Sunset Status
Documents original Safe contract versions, known limitations, and current operational status. Critical for teams maintaining legacy deployments to understand security posture and migration urgency. Chainscore can assess legacy deployment risk and recommend migration paths.
