Digital asset fork management is the set of policies and procedures an institution follows when a blockchain it supports undergoes a fork. A contentious hard fork can produce a chain split, leaving two networks and two assets where there was one. A custodian, exchange or fund manager has to decide which chain keeps the original name and ticker, and whether it will support the new asset at all.
The process resembles corporate action handling. The firm monitors announcements, assesses the technical safety, liquidity and legal status of each chain, and tells clients its decision in advance. Around the fork it may pause deposits and withdrawals, take a snapshot of balances, and wait for replay protection before moving funds. If it supports the new asset, it credits clients or enables withdrawal; if not, its terms state what happens. Similar steps apply to an airdrop. Policies form part of wallet governance and digital asset custody agreements.
