A Solana token backed by physical pre-1965 US silver dimes. Each SDIME represents the silver content of one authentic silver dime — 0.07234 troy ounces of fine silver.
silverdime is a Real World Asset (RWA) token on Solana. Unlike algorithmic stablecoins or purely speculative tokens, each SDIME in active circulation is backed 1:1 by a physical pre-1965 US silver dime held in the issuer's reserve.
Pre-1965 US dimes — both Mercury (1916–1945) and Roosevelt (1946–1964) varieties — are composed of 90% silver and 10% copper. None are clad. Every coin in the reserve is genuine US silver coinage.
In 1965 the US Mint switched dimes to a copper-nickel clad composition containing zero silver. Every dime minted before 1965 is 90% silver — there are no exceptions, no varieties to check, no confusion. Pre-1965 is a bright line that makes the backing unambiguous.
| Type | Years | Composition | Silver oz per coin |
|---|---|---|---|
| Mercury Dime (Winged Liberty) | 1916–1945 | 90% Ag, 10% Cu | 0.07234 |
| Roosevelt Dime | 1946–1964 | 90% Ag, 10% Cu | 0.07234 |
The issuer also holds $90 face value in other pre-1965 US silver coinage (quarters and halves) which may be used as supplementary collateral as the project grows. These coins contain approximately 65 troy ounces of additional silver.
silverdime has a fixed total supply of 1,000,000,000 SDIME. The mint authority has been permanently revoked — no additional tokens can ever be created. This is verifiable on-chain.
| Wallet | Tokens | % of Supply | Status | Purpose |
|---|---|---|---|---|
| Issuer wallet | 300 | < 0.001% | Active | Silver-backed, 1:1 with physical dimes |
| Deep reserve | 999,999,700 | ~100% | Locked | Released only as silver backing grows |
The reserve holds tokens that are not yet backed by physical silver. They will only be released into circulation as additional silver coins are added to the physical reserve — maintaining the 1:1 backing ratio for all circulating tokens. Tokens in the reserve represent future capacity, not circulating supply.
The deep reserve wallet exists to allow the project to scale as additional physical silver is acquired. The release policy is strict:
One SDIME token is released from the reserve for every one additional pre-1965 silver dime added to the physical backing. No tokens will be released speculatively, for liquidity incentives, or for any purpose other than matching new physical silver.
Everything about silverdime is publicly verifiable on the Solana blockchain. You do not need to trust the issuer's word — you can check the facts yourself.
Photographs and video of the physical silver reserve will be published here at launch. The reserve will be re-documented whenever new silver is added and new tokens are released.
