Comprehensive evaluation of the token
Synapse (SYN) is an established decentralized cross-chain bridge and messaging protocol that has transitioned into a legacy asset. Development activity throughout 2025 and 2026 has completely stalled, with no verified on-topic updates or shipping signals. Governance and community engagement have similarly dried up following the passage of governance proposal SIP-43 in early 2025, which approved a migration from SYN to a successor token (CX) at a 1:5.5 ratio with a migration deadline of February 2026. Because that deadline has passed, SYN is functionally deprecated and structurally impaired regarding ongoing utility and value capture. Note that the Security and Audit History section had insufficient data (-1.0) due to search collision with unrelated entities, and its weight was redistributed across the active sections. In accordance with the deprecated/migrated token rule, SYN is evaluated as an obsolete legacy asset.

About Synapse (SYN)
Synapse (SYN) is a legacy token that was deprecated following a community-approved migration to a successor token, CX, initiated via governance proposal SIP-43 in early 2025. Originally created as the native utility and governance asset for the Synapse Protocol, SYN operates as an ERC-20 token deployed across multiple blockchain networks, including Ethereum, Arbitrum One, Optimism, Base, Polygon PoS, BNB Smart Chain, Avalanche, and Fantom. The protocol was established as a decentralized cross-chain bridging and messaging network designed to address liquidity fragmentation across EVM and non-EVM environments.
Within the network architecture, SYN was designated for governance voting, protocol fee settlement, and liquidity provider incentives. The token has a fixed total supply of approximately 250 million units with roughly 88% of the supply in circulation. Governance was executed through a decentralized autonomous organization (DAO) using Snapshot, though administrative control required a high submission threshold of 550,000 SYN, and project documentation provides no public team information.
SYN faces severe structural impairment and operational obsolescence. Proposal SIP-43 established a migration ratio of 1 SYN to 5.5 CX with a migration deadline of February 2026, marking SYN's transition into an unsupported legacy token. The project recorded no verified development activity or protocol updates throughout 2025 and 2026, while community and governance participation ceased after the migration proposal. In secondary markets, SYN suffered a price decline of approximately 98% from its all-time high alongside near-total liquidity depletion in late 2025.
