Synapse SYN

What SYN actually is on-chain

Synapse is an ERC-20 deployed on Optimism, at contract address 0x5a5fff6f753d7c11a56a52fe47a177a87e431655. That address, not the ticker SYN, is what uniquely identifies this asset: anyone can deploy a second token calling itself SYN, but the contract is unforgeable. Verify it against optimistic.etherscan.io before sending funds or approving a spend.

Because it lives on Optimism, SYN is held in any EVM-compatible wallet, transfers are paid for in ETH rather than in SYN itself, and secondary liquidity sits in Velodrome and Uniswap pools. Two consequences follow for anyone setting alerts: you need ETH in the same wallet to move the token at all, and a quoted price taken from a pool is a pool price — it includes slippage that an order-book quote would not.

For SYN the project publishes an active account as @SynapseProtocol. That is a partial paper trail — enough to check claims against, not enough to audit. None of it is a quality judgement about the asset; it is simply what can be independently checked before the chart is worth looking at.

Where SYN sits in the market

Ranked #1124, Synapse falls in the upper small-cap band. The order book absorbs size poorly at this depth: one meaningful market order can reprice the tape by several percent before it retraces minutes later. A lone static price target therefore fires on noise, and what you want is a condition built to survive that wick. Venue coverage is narrow, which makes volume-based delisting a concrete risk rather than a theoretical one.

CryptoPingAi is currently streaming 3 live SYN order books (Binance, Gate.io, HTX). That is coverage in line with a #1124 ranking: enough books to cross-check a quote, few enough that one of them can dominate price formation for hours at a time. None of the books we see for SYN are regulated US or Korean venues, so this is an offshore-quoted asset — availability, and the price itself, depend on which jurisdiction you trade from.

SYN against its all-time high

More than 95% separates SYN from its all-time high of $4.92 (on 2021-10-24) — a 31.3x recovery. At that distance the high stops working as a reference at all; it belongs to a different supply structure, a different holder base and typically a different cycle. What carries information for SYN now is the downside, so read the range section below before this one. It was set 5 years ago. A reference that old says more about the cycle it belongs to than about the asset as it trades now.

SYN across its historical range

SYN has traded across a 113x range, between $0.0434 and $4.92. Any volatility figure quoted for this asset depends heavily on which part of that range it is measured over.

SYN trades roughly 3.63x above its record low of $0.0434 (on 2026-03-31). Recovery from the bottom has been limited, which means the low is still close enough to function as a real reference level rather than a historical footnote.

SYN supply and valuation data

Synapse sits just outside the band where circulating and total supply are independently verified, so we hold a valuation figure for SYN but not an audited token count. What we do have is a fully diluted valuation of $14.6 million as of 2026-05-12. That is in the upper quartile of tracked assets by fully diluted value.

Since the figure is a snapshot rather than a live number, we do not reverse it into a supply count: the price has moved since it was taken, and that division would produce a confident but incorrect token count. For any per-token valuation, check the current supply on the project's own explorer first. The authoritative figure is the one optimistic.etherscan.io reports for this contract.

What kind of asset SYN is

Synapse is an infrastructure asset — the category that includes oracles, data availability, storage and physical-infrastructure networks. Demand for these is derived rather than direct: it depends on how much is being built on top, which makes revenue steadier but growth slower than in consumer-facing categories. Token value accrual is often the weakest link and is worth verifying before assuming it exists.

CoinGecko files SYN under 10 categories, including BNB Chain Ecosystem, Avalanche Ecosystem, Polygon Ecosystem, Fantom Ecosystem, Arbitrum Ecosystem. CoinGecko also records deployments on BNB Chain (2,027 tracked tokens), Avalanche (256 tracked tokens), Polygon (531 tracked tokens), so on-chain liquidity is split across several networks and the cheapest venue depends on which deployment you are trading.

How to set a Synapse alert that is worth receiving

Synapse is the ERC-20 at 0x5a5f…1655 on Optimism — quoted on 3 venues we stream — high dated 2021-10-24 — rank #1124. On this profile the condition that carries signal is thresholds anchored to the recent range rather than to the all-time high.
