SLP (Simple Ledger Protocol) tokens are tokens built on the Bitcoin Cash blockchain, similar to ERC-20 tokens on Ethereum or SEP-20 tokens on SmartBCH.

They use OP_RETURN opcodes to store the data, since Bitcoin Cash does not have a native way to create tokens. There are discussions to create native tokens on Bitcoin Cash, like "group tokenization" [1] and PMv3 [2]

These tokens are not miner-vlaidated and therefore it's possible to accidentally burn them. If you load your private key to non-SLP compatible wallet, your tokens will seem like dust to the wallet (546 satoshis) and will will send them as BCH, effectively burning SLP tokens.

Some of the most well-known tokens: FlexUSD, Spice, HONK, USDT
