The token represents one specific French fund share
gbpSAFO is the GBP accumulation share of Spiko Amundi Overnight Swap Fund, with ISIN FR0014015LF8. It is one share class of the French-law Spiko SICAV. It is not Spiko’s separate UK Treasury-bill fund, and the other currency classes inside SAFO are not the same security. The ISIN resolves those look-alike names.
A holder owns a proportional interest in the pooled UCITS assets and receives one vote for each share. The token is the register entry for that legal share on an approved distributed ledger. It is not a bank deposit, a pound reserve or direct ownership of a particular bond in the portfolio.
