Harvest.art vs. Unsellable: NFT Tax-Loss Harvesting Compared

Harvest.artMay 1, 2026Updated October 20, 2026

TL;DR

Harvest.art is the original NFT tax-loss harvesting service, launched in 2021. On Ethereum it charges a single flat 0.02 ETH service fee per batch (regardless of size), it supports 10 EVM chains, and operates a public on-chain auction layer (The Barn) where harvested NFTs continue trading.

Unsellable launched in 2022. It charges 0.002 ETH per NFT (capped at 0.08 ETH per transaction), supports Ethereum only, and warehouses harvested NFTs.

The fee math breaks even at roughly 10 NFTs. Below that, the two are close. Above that, Harvest's flat fee scales better and keeps getting cheaper per NFT as the batch grows. Multi-chain wallets only have one option: Harvest is the only platform with native L2 and alt-EVM support.

The side-by-side

	Harvest.art	Unsellable
Founded	2021 (original)	Late 2022
Price paid per NFT	1 gwei	1 penny (paid in ETH)
Service fee structure	Flat 0.02 ETH per batch on Ethereum (any size, up to 500 items)	0.002 ETH per NFT (capped at 0.08 ETH per transaction)
Fee at 10 NFTs	0.02 ETH (flat)	0.02 ETH (~breakeven)
Fee at 40 NFTs	0.02 ETH (flat)	0.08 ETH (cap reached)
Fee at 500 NFTs	0.02 ETH (flat)	0.08 ETH (capped)
Supported chains	Ethereum, Polygon, Arbitrum, Optimism, Base, Blast, Avalanche, ApeChain, Robinhood Chain, Abstract	Ethereum only
Asset types	ERC-721, ERC-1155, ERC-20	ERC-721, ERC-1155
Batch size	Up to 500 items per transaction	Up to 500 items per transaction
What happens to harvested NFTs	Listed in The Barn; available via 24-hour on-chain auctions	Held in the platform's collection
Bid tickets / rewards	Free bid ticket per item harvested	None
Onchain transparency	Open source frontend; Etherscan-verified contracts	Etherscan-verified contracts
Cumulative losses realized	$190M+ USD	Not publicly disclosed

Real-world cost comparison

Pricing in the abstract is hard to feel. Here are two transactions users have publicly described, both run during the December 2024 year-end harvesting rush:

Platform	NFTs sold	Total cost (gas + fees)	Cost per NFT
Harvest.art	459	~$300	~$0.65
Unsellable	80	~$630	~$7.88

The cost-per-NFT gap is roughly 12x. The gap shrinks for very small batches (where Harvest's flat batch fee dominates) and widens for large batches (where Unsellable's per-NFT fee dominates, even with the per-transaction cap).

Where Harvest.art wins

Original. Launched in 2021. Operating history matters for tax documentation, audit defensibility, and trust.
Multi-chain. Eight EVM networks. If you bought NFTs on Polygon during the cheap-mint era, on Base during the recent wave, or on ApeChain or Blast more recently, Harvest is the only platform that handles them natively.
Flat fee instead of per-NFT. A single 0.02 ETH batch fee covers up to 500 items. The per-NFT cost drops as your batch grows; with 100 NFTs you pay 0.0002 ETH effective per item. With Unsellable's cap, you bottom out at 0.0016 ETH per item — eight times more.
Productive secondary market. The Barn turns harvested NFTs into a public, on-chain auction layer that anyone can start. Outbid rewards, bid tickets, and 100% on-chain settlement keep the ecosystem alive instead of warehousing it.
ERC-20 token support. Most competitors handle only NFTs. Harvest also lets you harvest losses on small, illiquid token bags from the same wallet.

Where Unsellable is reasonable

Mainstream press coverage. Unsellable has been featured in major outlets and prominently displays tax professional endorsements on its homepage. If those signals matter to you, they have invested in them.
Polished consumer flow. A simple five-step process and a tax savings calculator front and center.
Affiliate program. A formal program for referrers.
Ethereum-only simplicity. If 100% of your NFT activity is on mainnet and your batch is small, the user experience differences are modest.

Which should you choose?

If you...	Choose	Why
Have NFTs across multiple chains	Harvest.art	Only platform with native L2 + alt-EVM support
Want to harvest 100+ NFTs at once	Harvest.art	Per-NFT cost drops dramatically at scale
Care about transparency and operating history	Harvest.art	Original since 2021, $190M+ realized, open frontend
Want to harvest illiquid ERC-20 tokens too	Harvest.art	Token support included; competitor is NFT-only
Have 5-20 NFTs all on Ethereum mainnet	Either works	Cost difference is small at this scale
Want a familiar marketing-page experience	Either works	Both have clean five-step flows

Frequently asked questions

Which platform is cheaper for NFT tax-loss harvesting?

For batches above roughly 10 NFTs, Harvest.art is cheaper. On Ethereum, Harvest charges a flat 0.02 ETH service fee per batch regardless of size (up to 500 items). Unsellable charges 0.002 ETH per NFT, capped at 0.08 ETH per transaction. The breakeven is at 10 NFTs. Above that, Harvest's flat fee wins; at the 40+ NFT range, Unsellable's cap is 4x Harvest's flat fee. In a publicly reported comparison, 459 NFTs on Harvest cost about $300 in total; 80 NFTs on Unsellable cost about $630.

Which platform supports more blockchains?

Harvest.art supports 10 EVM chains: Ethereum, Polygon, Arbitrum, Optimism, Base, Blast, Avalanche, ApeChain, Robinhood Chain and Abstract. Unsellable operates on Ethereum only. If your NFTs are spread across L2s and alt-EVMs, Harvest is the only platform that supports them natively.

Which is older?

Harvest.art launched in 2021 and is the original NFT tax-loss harvesting service. Unsellable launched in late 2022. Operating history matters for tax documentation and trust signals: Harvest has helped users collectively realize $190M+ in losses since launch.

Do both platforms produce IRS-style transaction receipts?

Yes. Both create on-chain transactions with timestamps and counterparty addresses that serve as evidence of an arms-length sale. The receipt is the on-chain transaction itself, exportable from any block explorer or imported automatically by tools like Awaken, Koinly, CoinLedger, CoinTracker, TokenTax, and ZenLedger.

Can I sell NFTs from multiple collections in one transaction?

Both platforms support batch sales. Harvest.art batches up to 500 items across multiple collections in a single transaction. Unsellable's transaction cap is similar.

What happens to the NFTs after I sell them?

On Harvest.art, sold NFTs are added to The Barn, a public catalog where anyone can start a 24-hour onchain auction by burning a bid ticket. You receive free bid tickets when you harvest. This means the NFTs stay productive in the secondary market rather than being warehoused. Unsellable keeps the NFTs in a held collection.

Should I worry about wash sale rules?

In the US today, wash sale rules generally do not apply to NFTs because the IRS classifies crypto as property, not securities. Legislation has been proposed to change this. The conservative move regardless: do not buy back the exact same token ID inside 30 days. Talk to a tax professional for advice specific to your situation.
