Blockchain Networks: Fees, Finality, Stablecoin Routes
The chains hub: eight networks compared on the facts that matter for moving stablecoins, from Ethereum and Tron to Base, Arbitrum, and Hyperliquid today.
Eight networks carry nearly all stablecoin movement. Each chain page states its consensus rules, its fee model, and its verified stablecoin roster as its own documents publish them. This hub compares them on finality, cost of sending, and L1 versus L2 design, and tracks the 2025 and 2026 entrants on dated facts.
What this hub covers
Stablecoins move on blockchains. The networks are not alike. A transfer that costs cents on one network can cost dollars on another. Finality differs by design. Finality is the point after which a payment cannot practically be reversed. Some networks are base layers that secure themselves. Others sit on top of a base chain and inherit their security from it.
This hub holds a page for each network the site covers. There are eight:
- Ethereum, the settlement layer and the largest stablecoin economy in the set
- Tron, the USDT-dominant network
- Solana, proof of history with fixed base fees
- BNB Smart Chain, fast finality with a documented roster gap
- Base, an OP Stack rollup
- Arbitrum One, a rollup with exposed fee legs
- Polygon PoS, a sidechain with checkpoints
- Hyperliquid, a layer 1 with one state
Each chain page states its consensus rules and its fee model. It lists the stablecoin roster only where the issuer’s own docs publish one, and it dates every on-chain pull. The layer 1 versus layer 2 page compares the settlement structures side by side, and the cost of sending page puts all eight networks’ stablecoin transfer costs in one dated table, every figure with its method and both providers.
Three designs that explain most of it
Ethereum secures itself with proof of stake. Validators stake capital and propose blocks. Dishonest validators lose their stake. The ethereum.org docs describe this model in full [4]. Solana pairs proof of stake with proof of history. Its own docs embed the design parameters in the page data they serve, including a 400 millisecond block time [7]. Tron uses delegated proof of stake. It prices usage through two resources, bandwidth and energy, not a single gas fee. The TRON developer docs state the burn rates and the order charges apply [6].
The layer 2 family
Base and Arbitrum One are rollups. They batch transactions. They post their data to Ethereum. They inherit Ethereum’s security for final settlement. The OP Stack docs that Base builds on state this model directly [8]. Polygon PoS describes itself differently, as a sidechain with checkpoint anchoring to Ethereum. That is a weaker security claim than a rollup makes, and its chain page keeps the difference visible. The layer 1 versus layer 2 page walks the whole distinction on facts.
What a chain page states, and refuses
Every chain page here follows one shape. Consensus and finality come from the chain’s own docs, quoted where the wording matters. Fees come from dated pulls against public nodes. A second provider cross-checks each pull. No fee figure appears without its capture date. Stablecoin addresses appear only where the issuer publishes them, checksum-verified where the format allows.
The refusals matter as much. No page ranks chains. No page projects capacity. Where a chain’s docs make a design claim, the page labels it a design claim, not a measurement. Where a launch date is not in the primary record, the page leaves it unstated. Three pages in this set carry exactly that refusal.
How cost is measured here
Fees are the most quoted and least dated numbers in this field. The library treats them as measurements, not as specs. A cost figure comes from a pull against a public node. It lands with the date of the pull. A second provider checks the same route the same day. When the two providers disagree, the page says so, and the disagreement stands as a finding rather than being averaged away.
Cost also depends on the route, not just the chain. The same asset can move as a native transfer or through a bridge, at different prices. The cost pages state the route each figure measures. A reader comparing two numbers from two pages can always see whether they measured the same thing.
The stablecoin routes
The two largest stablecoins split unevenly across these networks. Tether’s own transparency render publishes per-chain circulation. The stablecoins hub reads those figures with their as-of stamps. Circle publishes a 37-network approved list for USDC, with per-chain terms. One entry, Tron, is approved for redemptions only. That is why USDC on Tron exists as its own correction page. The Tron chain page covers the network side of the same story.
The 2025 and 2026 entrants, on dated facts
New chains now carry stablecoin value at the billion-dollar scale without having pages of their own yet. The table records what is verified as of 11 September 2026. Each row names what could not be verified, because on entrants the negatives carry the discipline.
| Entrant | Issuer-listed stablecoins, dated | Chain total, provider | Not verified |
|---|---|---|---|
| Plasma | Native USDC and EURC rows in Circle’s tables [1] [2] | $1,075,556,311.65 [5] | Consensus, finality, and fee fields. The chain’s docs and RPC hosts were unreachable at the research date |
| X Layer | Native USDC, with the issuer’s own footnote separating a bridged USDC.e it does not back [1]. Chain ID 196 confirmed on the public RPC [9] | $1,694,746,489.11 [5] | Architecture claims. The docs host is offline. The docs source repository is the record in use |
| Robinhood Chain | Zero mentions on all three issuer surfaces, Circle USDC, Circle EURC, and Tether [1] [2] [3] | $1,036,746,325.52 [5] | Everything beyond the provider row. No issuer documentation host was reachable |
The entrant rows are thin by finding, not by omission. When the documentation routes come back, the fields fill from primary sources. Until then, this table refuses to guess what the docs would say.
Where this hub sits
Bitcoin runs on its own network. The bitcoin hub covers it. Spending across chains is the spend hub’s subject. The basics and the glossary live at cryptocurrency. The rules that govern all of it start at regulation. Each hub links the others, so the trail never dead-ends.
