TL;DR
Ethereum remains the deepest, most secure ecosystem for high-value DeFi (~$55B+ TVL, 30,000+ developers) but costs $0.10–$30 per transaction. Solana is the fastest and cheapest general-purpose chain (thousands of real-world TPS, ~$0.00025 per transaction) and has become the default for consumer apps and high-frequency use cases. Stellar is the specialist: purpose-built for payments and stablecoins, with fees around $0.00001 and ~5-second finality, and its Soroban smart contract layer (Rust + WebAssembly) is newer and narrower in scope than the other two. The right choice depends entirely on what you’re building, not which chain is “better.”
If you’re deciding where to build in 2026, the honest answer is that Ethereum, Solana, and Stellar aren’t really competing for the same job anymore. They’ve diverged into different bets on what a blockchain should optimize for — and picking the wrong one for your use case will cost you more in the long run than any tutorial will teach you to avoid. Here’s what the current data actually says.
The headline numbers
Figures vary somewhat by source and month crypto data moves fast, and different trackers (DeFiLlama, Chainspect, Electric Capital) measure slightly differently but the relative picture is consistent across every source: Ethereum wins on depth and security, Solana wins on raw speed and cost at scale, Stellar wins on cost-per-transaction and simplicity for payment-shaped problems.
Ethereum processes roughly 15–30 transactions per second at the base layer, with fees typically running $0.10–$0.30 per transaction and spiking to $15–30 during congestion. Blocks settle in about 12 seconds, layered with additional security assumptions. Smart contracts are written in Solidity the most mature language in the space and the ecosystem carries over 30,000 active developers, $55–78 billion in DeFi TVL across the base layer and its Layer 2s, and more than 900,000 validators.
Solana processes roughly 2,000–5,000 transactions per second in real-world conditions (with a theoretical ceiling of 65,000 TPS), at a consistent fee of about $0.00025 per transaction regardless of network load. Finality lands in well under ten seconds — sub-second soft confirmation, with hard finality around 6.4 seconds. Contracts are written in Rust, typically via the Anchor framework, and the ecosystem has grown to around 17,000+ active developers, $8–12 billion in DeFi TVL, and 800–1,500 validators.
Stellar processes roughly 1,000–2,000 transactions per second, with a base fee of about $0.00001 per operation a fraction of a cent, consistently, without congestion spikes. Ledgers close about every 5 seconds with effectively instant finality on inclusion. Smart contracts run through Soroban, Stellar’s Rust-based, WebAssembly-compiled contract layer, on a network secured by a smaller federated set of roughly 90 validators. Stellar’s ecosystem is deliberately narrower and more specialized than the other two, with minimal DeFi TVL by design it isn’t trying to compete there.
Ethereum: the settlement layer
Ethereum’s architecture is deliberately conservative. The base layer processes roughly 15–30 transactions per second and settles in 12-second blocks — slow by design, because Ethereum treats decentralization and security as the priority and pushes speed to Layer 2 networks like Arbitrum and Base instead. That trade-off shows up directly in cost: a simple transfer on Ethereum mainnet typically runs $0.10–$0.30, and complex DeFi interactions can spike to $15–30 during congestion, before Layer 2 rollups bring it down.
What you get for that cost is depth. Ethereum carries roughly $55–78 billion in DeFi TVL across its base layer and L2 ecosystem, has over 900,000 validators, and hosts the largest developer community of any smart contract platform — over 30,000 active developers by Electric Capital’s count, plus the most extensive library of audited Solidity contracts and tooling anywhere in the space. If you’re building something that needs deep liquidity, institutional trust, or integration with existing DeFi infrastructure, Ethereum’s ecosystem gravity is hard to replicate elsewhere.
Build on Ethereum if: you’re building regulated financial products, need deep liquidity or composability with existing DeFi protocols, or your users can tolerate higher per-transaction costs in exchange for maximum security and decentralization.
Solana: the high-performance execution layer
Solana takes the opposite bet. Instead of layering scaling solutions on top, it scales the base layer itself targeting a theoretical maximum of 65,000 TPS through its Proof of History design, with real-world sustained throughput in the 2,000–5,000 TPS range during peak activity. Fees sit around $0.00025 per transaction regardless of congestion, which is roughly four orders of magnitude cheaper than an Ethereum mainnet swap.
That speed and cost profile is why Solana has become the default for consumer-facing crypto applications: retail DeFi trading, NFT minting, on-chain games, and micropayments, where a multi-dollar gas fee would kill the product outright. The trade-off is a smaller validator set (800–1,500, versus Ethereum’s 900,000+) and a rockier reliability history Solana’s last major network outage was in February 2024, though the newer Firedancer client (built by Jump Crypto, live on mainnet since 2024) has meaningfully improved resilience since then. Development happens primarily in Rust, typically through the Anchor framework, which has a steeper initial learning curve than Solidity but rewards it with genuinely high performance.
Build on Solana if: you’re building a consumer app, game, or anything with frequent small transactions where Ethereum-level fees would be a non-starter, and you’re comfortable with Rust.
Stellar: the payments and stablecoin specialist
Stellar is the one most builders coming from Ethereum or Solana haven’t spent real time with, and it’s worth understanding because it’s optimized for a narrower, specific job: moving money. Its Federated Byzantine Agreement consensus (the Stellar Consensus Protocol) closes a ledger roughly every 5 seconds with effectively instant finality once included, and its base transaction fee is about 0.00001 XLM per operation — a fraction of a cent, consistently, without the congestion spikes that hit Ethereum.
For a long time, Stellar wasn’t a general-purpose smart contract platform at all — it was a payments rail with a built-in asset-issuance model, which is why Circle chose it for native USDC and EURC, and why MoneyGram launched its MGUSD stablecoin on Stellar in June 2026. That changed with Soroban, Stellar’s smart contract platform, live on mainnet since March 2024. Soroban contracts are written in Rust and compiled to WebAssembly, with a deliberately narrow, resource-metered execution environment Stellar’s own documentation is explicit that contracts can’t use the full Rust standard library or most third-party crates, by design, to keep contracts predictable and secure. Soroban is additive to Stellar’s existing payment rails rather than a replacement for them, and Stellar’s own guidance still recommends issuing simple tokens as native Stellar assets rather than Soroban contracts, reserving Soroban for cases that actually need programmable logic mint/burn rules, multi-sig conditions, oracle-driven logic, compliance hooks.
Build on Stellar if: you’re building payments, remittances, or stablecoin infrastructure specifically, where sub-cent fees and fast, predictable finality matter more than a large existing DeFi ecosystem or NFT/gaming tooling.
The decision framework
Strip away the tribalism and the choice mostly comes down to three questions:
- What does your product actually need to do? Payments and stablecoin rails → Stellar. Consumer apps, games, high-frequency trading → Solana. Deep DeFi composability, institutional integration, maximum security assumptions → Ethereum.
- What can your users tolerate paying per transaction? If your product involves frequent small transactions, Ethereum’s base-layer fees alone can make the product non-viable before you’ve written a line of business logic.
- What language and ecosystem maturity do you want to build in? Solidity’s tooling and audited-library depth on Ethereum is unmatched; Rust is shared between Solana and Stellar but used in meaningfully different execution environments, so experience on one doesn’t fully transfer to the other.
None of these chains is trying to “win” the same race anymore. Ethereum is betting on being the trust layer everything else settles against. Solana is betting that most builders want raw performance in a single environment. Stellar is betting that the biggest real-world blockchain use case is still just moving money cheaply and reliably. Build for the job you actually have, not the chain with the loudest community.
