Stablecoin Supply & Liquidity Dashboard

How the Stablecoin Supply & Liquidity Dashboard works

Shows whether the supply of USDT, USDC and DAI on Ethereum mainnet is expanding or contracting, using ERC-20 totalSupply read directly from the token contracts. Useful for tracking on-chain dollar liquidity from a verifiable source.

What you enter

• None; data loads automatically from a cache of up to 30 minutes.

What it shows

• Combined USDT + USDC + DAI supply on Ethereum mainnet (USD)
• Snapshot block number, scope and data source (configured RPC or public JSON-RPC fallback)
• Bar chart of each token's current supply and its share of the total
• Line chart of site-collected daily snapshots of total supply (appears once two or more days exist)

How to use it

1. Read the Combined supply tile for the current total of the three tokens.
2. Check the Snapshot block to see which Ethereum block the reading came from.
3. Use the current supply composition bars to see each token's share.
4. Scroll to the site-collected daily history to see whether the total is rising or falling.
5. Cross-check with the stablecoin depeg tool before interpreting it.

Formula

Token supply = totalSupply() / 10^decimals (USDT 6, USDC 6, DAI 18); combined = USDT + USDC + DAI; share = token / combined × 100.

Worked example

Hypothetical reading: USDT 50 billion USD, USDC 40 billion USD, DAI 5 billion USD. Combined = 50 + 40 + 5 = 95 billion USD. USDT share = 50 / 95 × 100 ≈ 52.6%; USDC ≈ 42.1%; DAI ≈ 5.3%.

How to read the result

• A rising combined line suggests more dollar liquidity is being issued on Ethereum mainnet.
• Composition shifts, such as a rising USDC share, can reflect changing issuer or user preferences.
• Read it alongside peg stability and overall risk appetite, not in isolation.

Limits and cautions

• It covers only three tokens on Ethereum mainnet, not other chains or the whole stablecoin market.
• Contract supply includes tokens in treasuries or idle wallets, so it is not the same as tradable liquidity.
• History starts when the site began saving snapshots, so long-term trends are not available yet.

Common questions

What is the total stablecoin supply?

This dashboard reports only USDT, USDC and DAI on Ethereum mainnet. Total stablecoin supply across all chains and issuers is larger; use this as a verifiable subset, not the full market.

How is supply measured?

The server calls each ERC-20 contract's totalSupply via eth_call and divides by the token's decimals. The snapshot block number is shown so the reading is reproducible.

If stablecoin supply rises, will crypto prices rise?

Not necessarily. More supply can mean more on-chain dollar liquidity, but it may sit idle or be used outside trading. It is context, not a price signal.
