How We Built Chainalysis’ Robust Knowledge Graph for Solana Transactions

Solana’s primary addresses are known as System Account Addresses and they have control over all addresses beneath them. Token Accounts come in two forms: Ancillary Token Accounts hold SPL tokens (the equivalent of ERC20s ) or NFTs. These accounts simplify SPL token transfers if recipients have multiple Ancillary Token Accounts with the same token. Additionally, users cannot send SPL tokens if recipients do not have Ancillary Token Accounts for the SPL tokens in question. Associated Token Accounts allow users to send SPL tokens even if recipients do not have Ancillary Token Accounts of that mint.
