Coinbase lists the ERC-20 token Spark (SPK), labeled as an "experimental" asset

according to a Coinbase announcement, the platform will support the Spark (SPK) token on the Ethereum network, labeled as "Experimental," and has opened the transfer feature. If liquidity conditions are met, the SPK-USD trading pair will be gradually launched later today, with some jurisdictions possibly having restrictions.

Coinbase reminds users not to send SPK through non-ERC-20 networks, as funds may be lost.
